All other distributions / relationships are assumed to be given by the empirical distribution function. Those are the parts that have been well studied and are unlikely to present surprises. It says: assume a parametric model for certain parts of the data. Simulate many realizations of the given estimator using Monte Carlo and compute its moments and other characteristics. Literally, assume that the true cumulative distribution function of the studied variables equals the empirical cumulative distribution function. Bootstrap says: assume that the true distribution of the data is the empirical distribution dictated by the current sample. Bootstrap is a way out when extra assumptions and derivations are not an option. The LCA Bootstrap Stata function can assist users in choosing the number of classes for latent class analysis (LCA) models. In order to illustrate it, I will use the same previous example where job satisfaction mediates the.
#Stata bootstrap how to
This post will show how to test a simple mediation model with one mediator using Stata and particularly using Structural Equation Modeling (SEM).
Therefore it seems problematic to learn anything about the distribution of the estimator, unless we can make parametric assumptions about the underlying data and the distribution of the estimator can be analytically related to the distribution of the data. In my previous post I introduced what mediation analysis means and how mediation is commonly tested. On any given sample any given estimator has only one value. and then panel bootstrap (this program) (3) Use Stata version 8 regress cluster. Bootstrap is a method of estimating variance and other characteristics of statistical estimators. Fixed Effects Estimation (xtreg command with fe option) by Stata FAQ.
