An introduction to hierarchical linear modeling - TQMP

These labels all describe the same advanced regression technique that is HLM. HLM simultaneously investigates relationships within and between hierarchical levels of grouped data,

www.gs.washington.eduFixed -vs- Random Effects Models •In ANOVA and Regression analyses our independent variables can be treated as Fixed or Random •Fixed Effects: variables whose levels are either sampled exhaustively or are the only ones considered relevant to the experimenter •Random Effects: variables whose levels are randomly sampled
Title stata.com regress — Linear regression
www.stata.comregress performs ordinary least-squares linear regression. regress can also perform weighted estimation, compute robust and cluster–robust standard errors, and adjust results for complex survey ... estimating treatment effects, and providing answers to public policy questions. For a mathematically rigorous treatment, seePeracchi(2001, chap. 6
Using the Margins Command to Estimate and Interpret ...
www3.nd.edu• Marginal effects are popular in some disciplines (e.g. Economics) because they often provide a good approximation to the amount of change in Y that will be produced by a 1-unit change in X k. With binary dependent variables, they offer some of the same advantages that the Linear Probability Model (LPM) does –they give you a single number that
