WebSep 13, 2024 · hout has an aic attribute that you can call using hout.aic The straight-out answer is to use hout.aic instead of hout.f_pvalue for Line 67. However, you need to re-specify the initial check value minfpv since 1.0 would be too small for AIC in this case. That is for Line 56. Try it out and see what the initial minfpv should be.
