{title:Description}

{pstd}
{cmd:svy: mlogit} fits multinomial logistic regression models for complex
survey data.  In the multinomial logistic regression model, {it:depvar} is a
discrete variable that takes on more than two outcomes that have no natural
ordering.  The model can have a maximum of 50 outcomes with Stata/SE or
Intercooled Stata and 20 outcomes with Small Stata.

{pstd}
See {helpb mlogit} for a description of this model involving nonsurvey data,
{helpb "svy: logistic"} for logistic regression reporting odds ratios,
{helpb "svy: logit"} for logistic regression,
{helpb "svy: probit"} for probit regression,
{helpb "svy: ologit"} for ordered logistic regression, and
{helpb "svy: oprobit"} for ordered probit regression for survey data.
