Hi,
Happy New Year!
Can you explain to me the meaning of the N and K in AIC formula. K is the number of the model parameters, and N is the number of datapoints? Am I right?
Kind regards,
Dominik |

Thank you. In formulas, n occurs in both cases (n and N). I am not pretty sure why. Is N used for normally distributed data?
Kind regards,

In the Statistics on Columns tool dialog, under the Computation Control tab, you can set different Varaicne Disisor of Moment --- DF, N, WDF, WS, WVR. The capital N in the page means using sample size n as the divisor to calculate the moment.
