Description:	Mplus is a statistical modeling program designed to analyze data. This technology offers various choices of models, estimators, and algorithms in a program that includes an interface and graphical displays of data and analysis results. Mplus allows the analysis of both cross-sectional and longitudinal data, single-level and multilevel data, data that comes from different populations with either observed or unobserved heterogeneity, and data that contains missing values. Analyses can be carried out for observed variables that are continuous, censored, binary, ordered categorical (ordinal), unordered categorical (nominal), counts, or combinations of these variable types. In addition, Mplus has capabilities for Monte Carlo simulation studies, where data can be generated and analyzed according to most of the models included in the program. This technology does not utilize a database as data is saved to the user`s local drive.
