Bollen-Stine bootstrap following confirmatory factor analysis

bollenstine,reps(#)saving(filename)cfaoptions(...)bootstrap_options

bollenstineperforms Bollen and Stine (1992) bootstrap following structural equation models (confirmatory factor analysis) estimation. The original data are rotated to conform to the fitted structure. By default,bollenstinere-estimates the model with rotated data, and uses the estimates as starting values in each bootstrap iterations. It also rejects samples where convergence was not achieved (implemented throughreject( e(converged) == 0)option supplied tobootstrap).

Options

reps(#)specifies the number of bootstrap replications. The default is 200.

saving(filename)specifies the file where the simulation results (the parameter estimates and the fit statistics) are to be stored. The default is a temporary file that will be deleted as soon asbollenstinefinishes.

cfaoptions(...)allows to transfer options tocfa. Some bootstrap replications may result in samples in which iterative maximization never converges, so in order to speed up computations, it might make sense to limit the number of iterations, say withcfaoptions(iter(20) ).

All non-standard model options, likeunitvarorcorrelated, must bespecified with bollenstine to produce correct results!All other options are assumed to be

bootstrap_optionsand passed through tobootstrap.
