Re: [R] stepAIC() that can use new extractAIC() function implementing AICc

I have found the problem and a solution. The problem comes from the functions addterm.glm() and dropterm.glm() from MASS package. They use extractAIC() without transmitting the ... argument: aic <- aic + (extractAIC(object, k = k)[2L] - aic[1L]) I replace the call with: aic <- aic + (extract

[R] stepAIC() that can use new extractAIC() function implementing AICc

I would like test AICc as a criteria for model selection for a glm using stepAIC() from MASS package. Based on various information available in WEB, stepAIC() use extractAIC() to get the criteria used for model selection. I have created a new extractAIC() function (and extractAIC.glm() and e
