Measures of fit -The Coefficient of Determination R2 -Standard Error of Estimate Su - Coefficient of random variation V
Coefficient of Determination, R 2 The coefficient of determination is the portion of the total variation in the dependent variable that is explained by variation in the independent variable In our example R 2 =0,8496. It means that 84 % of the total variation of the number of born baby´s is explained by the trend model .
