R Documentation
Converts a dataset imputed by MIMCA or MIPCA into a mids object
Description
This function performs grouping and sorting operations on a multiply imputed dataset. It creates a mids object that is needed for input to with.mids, which allows analyse of the multiply imputed data set. The original incomplete data set needs to be available so that we know where the missing data are.
Usage
prelim(res.mi,X)
Arguments
res.mi
an output of the functions MIPCA or MIMCA
X
the original incomplete data set corresponding to the res.mi argument
## Not run:
data(TitanicNA)
## First the number of components has to be chosen
## (for the reconstruction step)
## nb <- estim_ncpMCA(TitanicNA,ncp.max=5) ## Time-consuming, nb = 5
## Multiple Imputation
res.mi <- MIMCA(TitanicNA, ncp=5, verbose=T)
#Analysis
imp<-prelim(res.mi,TitanicNA)
fit <- with(data=imp,exp=glm(SURV~CLASS+AGE+SEX,family = "binomial"))
#Pooling
res.pool<-pool(fit)
summary(res.pool)
## End(Not run)
