Independent variables. The equation of the fitted model is

LOG(Y) = 1,27574*LOG(K) - 0,63678*LOG(L) - 0,00421414*time

Since the P-value in the ANOVA table is less than 0.01, there is a

statistically significant relationship between the variables at the

99% Confidence level.

The R-Squared statistic indicates that the model as fitted

explains 99,9975% of the variability in LOG(Y). The adjusted

R-squared statistic, which is more suitable for comparing models with

different numbers of independent variables, is 99,9973%. (Note: since

the model does not contain a constant, you should be careful in

interpreting the R-Squared values. Do not compare these R-Squared

values with those of models which do contain a constant.) The

standard error of the estimate shows the standard deviation of the

residuals to be 0,0427644. This value can be used to construct

prediction limits for new observations by selecting the Reports option

from the text menu. The mean absolute error (MAE) of 0,0303906 is the

average value of the residuals. The Durbin-Watson (DW) statistic

tests the residuals to determine if there is any significant

correlation based on the order in which they occur in your data file.

Since the DW value is less than 1.4, there may be some indication of

serial correlation. Plot the residuals versus row order to see if

there is any pattern which can be seen.

In determining whether the model can be simplified, notice that the

highest P-value on the independent variables is 0,1065, belonging to

LOG(L). Since the P-value is greater or equal to 0.10, that term is

not statistically significant at the 90% or higher confidence level.

Consequently, you should consider removing LOG(L) from the model.
