Importance weights PreviousNext

could you tell me if Mplus has a command to apply importance weights.

This would be equivalent to -iweight- in Stata or -caseweight- in Latent Gold.

I have 960 cases, and 4 rows per subject with my weighting summing to 1 within subject.

If I use the weight variable as a sampling weight, then the weights are rescaled such that my sample appears to be 3840 (i.e. the number of rows in my dataset).

many thanks, Jon

Would the FREQWEIGHT option help you? See the user's guide for a description.

Hi Linda,

looks like FREQWEIGHT requires the weights to be integers, whilst my weights are fractions and sum to one within each individual.

Then we can't help you at this time.

Hi Linda,

that's a shame.
I'll have to put it on my list for Santa

thanks, Jon
