SYNOPSIS ^

function [FPE,AIC,BIC,SBC,MDL,CATcrit,PHI,optFPE,optAIC,optBIC,optSBC,optMDL,optCAT,optPHI,p,C]=selmo(e,NC);

DESCRIPTION ^

 Model order selection of an autoregrssive model
 [FPE,AIC,BIC,SBC,MDL,CAT,PHI,optFPE,optAIC,optBIC,optSBC,optMDL,optCAT,optPHI]=selmo(E,N);

 E    Error function E(p)
 N    length of the data set, that was used for calculating E(p)
 show  optional; if given the parameters are shown

 FPE    Final Prediction Error (Kay 1987, Wei 1990, Priestley 1981  -> Akaike 1969)
 AIC    Akaike Information Criterion (Marple 1987, Wei 1990, Priestley 1981 -> Akaike 1974)
 BIC    Bayesian Akaike Information Criterion (Wei 1990, Priestley 1981 -> Akaike 1978,1979)
 CAT    Parzen's CAT Criterion (Wei 1994 -> Parzen 1974)
 MDL    Minimal Description length Criterion (Marple 1987 -> Rissanen 1978,83)
 SBC    Schwartz's Bayesian Criterion (Wei 1994; Schwartz 1978)
 PHI    Phi criterion (Pukkila et al. 1988, Hannan 1980 -> Hannan & Quinn, 1979)
 HAR    Haring G. (1975)
 JEW    Jenkins and Watts (1968)

 optFPE     order where FPE is minimal
 optAIC     order where AIC is minimal
 optBIC     order where BIC is minimal
 optSBC     order where SBC is minimal
 optMDL     order where MDL is minimal
 optCAT     order where CAT is minimal
 optPHI     order where PHI is minimal

 usually is 
 AIC > FPE > *MDL* > PHI > SBC > CAT ~ BIC
