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
