What is the difference between mixed and Xtmixed Stata?
xtmixed has been renamed to mixed. xtmixed continues to work but, as of Stata 13, is no longer an official part of Stata. This is the original help file, which we will no longer update, so some links may no longer work.
What is Meglm Stata?
meglm fits multilevel mixed-effects generalized linear models. meglm allows a variety of distributions for the response conditional on normally distributed random effects.
What is Melogit?
Description. melogit fits mixed-effects models for binary and binomial responses. The conditional distribution of the response given the random effects is assumed to be Bernoulli, with success probability determined by the logistic cumulative distribution function.
What is linear mixed model analysis?
Linear mixed models are an extension of simple linear models to allow both fixed and random effects, and are particularly used when there is non independence in the data, such as arises from a hierarchical structure. For example, students could be sampled from within classrooms, or patients from within doctors.
What is multilevel logistic regression?
The general aim of multilevel logistic regression is to estimate the odds that an event will occur (the yes/no outcome) while taking the dependency of data into account (the fact that pupils are nested in classrooms).
What is Xtlogit?
Description. xtlogit fits random-effects, conditional fixed-effects, and population-averaged logit models for a binary dependent variable. The probability of a positive outcome is assumed to be determined by the logistic cumulative distribution function. Results may be reported as coefficients or odds ratios.

When should I use linear mixed model?
When would you use a mixed model?
Mixed Effects Models are used when there is one or more predictor variables with multiple values for each unit of observation. This method is suited for the scenario when there are two or more observations for each unit of observation.
When should I use multilevel Modelling?
Multilevel models are particularly appropriate for research designs where data for participants are organized at more than one level (i.e., nested data). The units of analysis are usually individuals (at a lower level) who are nested within contextual/aggregate units (at a higher level).
