hello
 I want to know why when I use the function "svyglm" for a logistic regression I get the AIC: NA. The code and the result is mestran below:

mod2<-svyglm(APES_DICOT~Nivel_Educativo+Ocupacion_principal+Afiliacion_salud+Tiene_cuidador+Presencia_enfer_cronica+
Consumo_tabaco+Consumo_alcohol+Presencia_Dolor+ABC_fis+ABC_instr+Anergia+Actividad_fisica_ultimo_año+
Disminucion_fuerza_agarre+Hospitalizacion_ultimo_año+Urgencias_ultimo_año+Miedo_caer,design=Muestra.comp,
family=quasibinomial(link="logit"))

error or warning:

Degrees of Freedom: 282 Total (i.e. Null);  28 Residual
  (32 observations deleted due to missingness)
Null Deviance:      323
Residual Deviance: 186.9        AIC: NA


thanks

Presumably based upon the same logic that Thomas (who you cc'd here) included in a post earlier today:

Also, please start a new thread when you post, rather than replying to an existing thread.
