    • Nonindependent sampling, matching, and assumptions about confounding
    • Within and between estimators
    • Random-intercept models
    • xtreg, xtmixed, and gllamm
  • Panel-data, random-coefficient, and multilevel models
    • Change score, ANCOVA, and growth curve models
    • Trajectory classes
    • Models with multiple levels


  • Generalized linear mixed modeling
    • Generalized linear models
    • Subject-specific and population-average models
    • The xt suite
  • Extension to latent variables
    • Introducing correlation among equations
      • Generalized instrumental-variables model

      • Multilevel factor models
    Introduction to programming with Mata (9:00 AM–1:00 PM)
    Alan Riley
    Bill Rising

    This course is an introduction to programming Mata, Stata’s fast, compiled matrix-programming language. The course will cover the basics of Mata, including types, operators, functions, and structures.

Mata’s power and speed as a programming tool for data management and statistics will be demonstrated.

    • Introduction to Mata
    • Types, operators, functions, and structures
    • Calling Mata from do- and ado-files
    • Data and file management
