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].
V vsaki analizi smo izdelali naslednje izračune:- cenilk ak;- standardne deviacije s(Y);- srednje standardne deviacije sm(Y);- standardne deviacije cenilk s(ak);- t-test t*;- koeficient večkratne določenosti R2;- srednje relativne napake em.Ker delamo z velikim številom podatkov, je vrednost R2 0,75 ali več primerna [11].
