Multiple imputation on subgroups
Dear R-users, I want to multiple impute missing scores, but only for a few subgroups in my data (variable 'subgroups': only impute for subgroups 2 and 3). Does anyone knows how to do this in MICE? This is my script for the multiple imputation: imp <- mice(data, m=20, predictorMatrix=pred, post=post, method=c("", "", "", "", "","norm", "norm","norm","norm","norm","norm"), maxit=20) . The final analysis should be on the dataset as a whole, so with subgroups 2 and 3...

MICE passive imputation formula
...'s give an example with BMI. I know, that if I want to use passive imputation for BMI, I can use the following command: meth["BMI"] <- "~I(weight/(height/100)^2)" pred[c("weight", "length"), "BMI"] <- 0 imp <- mice(Data, method = meth, predictorMatrix = pred, maxit = 10, m = 5) But what If the formula for a variable is much more complicated, like with CKD-epi. The formula is: egfr_crea_ckdepi = function(creatinine, age, is_female, is_male) { if (length(creatinine) != length(age) || length(creatinine) != length(is_female) || lengt...

disculpe las molestias ...ayuda con MICE
Saludo gente, antes que nada gracias por la ayuda que puedan aportarme, soy iniciante en R, estoy usando el paquete Mice para realizar imputaciones múltiples sobre variables en su mayoría categóricas. El problema está que cuando expresó este comando imp <- mice(dataset,method="polr",maxit=1) donde el dataset es un data.frame me tirá este error : iter imp variable 1 1 pial1a
