(e) The estimated time of the event that triggered the request, with an indication of the possible margin of error;

(a) The estimated geographical and vertical co-ordinates of the location of the event that triggered the request with an indication of the possible margin of error;

(b) the data obtained from the calibration of tanks and instruments and from sampling and analyses, the procedures to control the quality of measurements and the derived estimates of random and systematic error;

The standard error of estimate (SE) of y on x and the coefficient of determination (r2) shall be calculated for each regression line.

if relevant, the associated estimation error of the corresponding estimates;

Since the estimators ak are known functions of Y, and the errors in Y are known, the errors in ak may be determined by error propagation.

An entity's estimates under IFRSs at the date of transition to IFRSs shall be consistent with estimates made for the same date under previous GAAP (after adjustments to reflect any difference in accounting policies), unless there is objective evidence that those estimates were in error.

In each analysis the following computations were performed:- the estimators ak;- the standard deviation s (Y);- the mean standard deviation sm (Y);- the standard deviation of the estimators s (ak); - the t-test t*;- the coefficient of multiple determination R2; - the mean relative error em.Since we deal with large sets of data, a value of 0.75 or more for R2 is desirable [11].

These models are expressed by the following general relation:(12).The estimators ak, the coefficient of determination R2, the standard deviation s(J) and the mean of the relative error em of these models are listed in Table 1.As an example, we took 12:00 on 21 December (t1= 1213, t2= 12) to compare the recorded value and the computed value.

Where the methods used by Member States in compiling the data involve sample methodology, the percentage standard error (95 % confidence) of the annual estimates for tonnes transported, tonne-kilometres performed and total kilometres travelled loaded for total goods road transport and for national goods road transport shall not be greater than ± 5 %.

In addition within the same timescale, the Member State shall provide Eurostat with the calculated figures of percentage standard error (95 % confidence) of the estimates for tonnes transported, tonne-kilometres performed and total kilometres travelled loaded for total goods road transport, for national goods road transport and for total international goods road transport.

Where the total stock of goods road motor vehicles relevant to the survey in a Member State is less than 25000 vehicles, or the total stock of vehicles engaged in international transport is less than 3000 vehicles, the percentage standard error (95 % confidence) of the annual estimates for tonnes transported, tonne-kilometres performed and total kilometres travelled loaded for total goods road transport and for national goods road transport shall not be greater than ± 7 %.

NCBs that choose a sampling approach for the selection of the reporting agents shall provide an estimate of the sampling error for the initial sample.

All data publications shall include technical information for each Member State on the effective sample size as well as a general indication of standard error of at least the main estimates.

In some instances, the differences may also indicate that the initial estimate for taxes and subsidies on products is subject to serious error, e. g. because the output of some product is underestimated.

The Member States concerned shall take suitable measures to limit and, where necessary, to estimate errors of observation for the total area under vines cultivated for each type of production use referred to in Article 2 (2) (B).

The choice between the different indirect procedures must above all take into account the minimization of the forecast error for the current year, in order that the provisional annual estimates correspond as closely as possible to the final figures.

The Transit Committee shall be convened in cases of serious deviations from the values estimated in Article 15 and Annexes VIII and IX which are attributable to system errors such as inaccurate assumptions, other technical or legal developments or which are caused by changes in the foreign trade situation arising from German unification or unforeseen practical implications of the point system.

An entity's estimates under IFRSs at the date of transition to IFRSs shall be consistent with estimates made for the same date under previous GAAP (after adjustments to reflect any difference in accounting policies), unless there is objective evidence that those estimates were in error.

For example, assume that an entity's date of transition to IFRSs is 1 January 2004 and new information on 15 July 2004 requires the revision of an estimate made under previous GAAP at 31 December 2003. The entity shall not reflect that new information in its opening IFRS balance sheet (unless the estimates need adjustment for any differences in accounting policies or there is objective evidence that the estimates were in error).

The correction of fundamental errors can be distinguished from changes in accounting estimates.

The calibration graph should be linear and pass through the origin, within twice standard error of Y-estimate.

A count of the number of kind-of-activity units registered to the population concerned in the business register corrected for errors, in particular frame errors, or an estimate if this type of unit is not registered.

The test is not valid unless the fiducial limits of error (P = 0,95) are not less than 50 % and not more then 200 % of the estimated potency.

By its nature, the revision of the estimate does not bring the adjustment within the definitions of an extraordinary item or a fundamental error.

It also specifies the accounting treatment for changes in accounting estimates, changes in accounting policies and the correction of fundamental errors.

Therefore, the effect of a change in the estimate of contract revenue or contract costs, or the effect of a change in the estimate of the outcome of a contract, is accounted for as a change in accounting estimate (see IAS 8, Net profit or loss for the period, fundamental errors and changes in accounting policies).

For example, the gain or loss recognised on the outcome of a contingency which previously could not be estimated reliably does not constitute the correction of a fundamental error.

the data obtained from the calibration of tanks and instruments and from sampling and analysis, the procedures to control the quality of measurements and the derived estimates of random and systematic error;

Describe statistical evaluation programmes for data accumulated in control programmes for weight, volume, sampling and analytical measurements (i.e. determination of the random and systematic errors of the measurements and associated limits of error); statistical methods used to combine individual measurement error estimates to obtain the overall limits of error for S/R differences, the book inventory, the physical inventory and MUF.

Describe methods of statistical evaluation of data accumulated in measurement control programmes for the evaluation of precision and accuracy of measurements and the estimation of measurement uncertainty (i.e. determination of the random and systematic errors of the measurements and the associated limits of error; statistical procedures used to combine individual measurement error estimates to obtain the overall limits of error for S/R differences, the book inventory, the physical inventory and MUF).

This leads to substantial uncertainties because of over- of underestimates (depending on the precise circumstances) and will increase the error margin of the GNP estimate in parallel with the growing importance of owner-occupied dwellings.

For Member States with a population of between one million and twenty million inhabitants, this requirement is relaxed so that the relative standard error for the estimate of quarterly changes shall not exceed 3 % of the sub-population in question.

In the case of a continuous survey, for sub-populations which constitute 5 % of the working age population the relative standard error at national level for the estimate of changes between two successive quarters, shall not exceed 2 % of the sub-population in question.

For a group of unemployed people representing 5 % of the working age population the relative standard error for the estimation of annual averages (or for the spring estimates in the case of an annual survey in the spring) at NUTS II level shall not exceed 8 % of the sub-population in question.

An enterprise discloses the nature and effect of a change in an accounting estimate that has a material effect in the current period or which is expected to have a material effect in subsequent periods in accordance with IAS 8, net profit or loss for the period, fundamental errors and changes in accounting policy.

Where the methods used by Member States in compiling the data involve sample methodology, the percentage standard error (95 % confidence) of the annual estimates for tonnes transported, tonne-kilometres performed and total kilometres travelled loaded for total goods road transport and for national goods road transport shall not be greater than ± 5 %.

In addition within the same timescale, the Member State shall provide Eurostat with the calculated figures of percentage standard error (95 % confidence) of the estimates for tonnes transported, tonne-kilometres performed and total kilometres travelled loaded for total goods road transport, for national goods road transport and for total international goods road transport.

Where the total stock of goods road motor vehicles relevant to the survey in a Member State is less than 25000 vehicles, or the total stock of vehicles engaged in international transport is less than 3000 vehicles, the percentage standard error (95 % confidence) of the annual estimates for tonnes transported, tonne-kilometres performed and total kilometres travelled loaded for total goods road transport and for national goods road transport shall not be greater than ± 7 %.

Comments should for example cover the selection procedure of these models (i.e. why a given model has been chosen in preference to alternative ones), if relevant the associated estimation error of the corresponding estimates, elements on the verification of the assumptions underlying the model, the test of the predictive power of the model using historical data, the comparison of the results generated by the model with other related sources of data, the use of screening and cross-validation studies, the tests of sensitivity of the model to parameters' estimation, the validation of the data inputs to the model.
