Re: Error when requesting residuals with many observations

Forgot to write that; I've tried only level 2, with and without batch, nopause, regular GUI (menus) and so on. I'll send you a dropbox link by email Chris, thanks

Error when requesting residuals with many observations

Apologies for flooding the forum, but I've met an error when requesting residuals for level 1 and level 2 in a normally distributed strictly hierarchical model. It only says "MLwiN has stopped working" or with runmlwin 's batch: "MLNScript has stopped working". Also tried experimenting with changing ...

Missing data: FIML and (multilevel) multiple imputation

Hi experts

I have >15% missing data in my continuous multilevel model; missing at independent variables at all levels but not the dependent variable on level 1. Paul Allison writes that Full-Information Maximum Likelihood has advantages compared with multiple imputation for single-level models ...

Re: Plausible values and complex survey design

In case others are having challenge#1 above, the pv module in Stata can be used with runmlwin. With some minor tweaks to the pv ado file it works like a charm.

Centring variables in 3+ level models

Hi all

There isn't much literature out there on centring in models with 3 or more levels. My model is continuous Y on level 1, with fixed effects predictors at all 4 levels (no random effects in my study). My main interest is a predictor on level 2. Levels are students -> classes -> schools ...

Re: Error message: Could not load plugin

Hi Chris et al

I also get the same bug as above, (Could not load plugin .... Using MLwiN 2.30, Stata 13.1, runmlwin is updated and I dog get my results from MLwiN, but the warning "getversion plugin could not be loaded" arises each time. Is this just a nuisance or will I continue to get everything ...

Plausible values and complex survey design

Hi Chris et al.

Is it possible to advocate for additions and prioritization for your (probably big) to-do list?
1. First and foremost, which should not be too difficult to implement: Selecting variables which are a set of plausible values (this exists in PISA, TIMSS, PIRLS, etc). The quick and ...

Re: Best fit line on predicted repeated measures lines in gr

Sorry, seems my emf pictures were discarded. Sorry about the unweildy graph size:
Predictions main.jpg

Actually, my question can be generalized to all predicted lines (not just repeated measures) when I think about it.
I should be more precise (and general) in my question: I want an overall best ...

Best fit line on predicted repeated measures lines in graphs

Hi all

So I have connected prediction lines for repeated measures (longitudinal) data (persons) and managed to graph these nicely. However, I was looking for a best fit line option for all these lines. This exists in Stata's xtline function, which I could use; however, Stata insists on colouring ...
