t-test Using STATA Software

Meta-analysis in Stata using gllamm.

There are several user-written programs for performing meta-analysis in Stata (Stata Statistical Software: College Station, TX: Stata Corp LP). These include metan, metareg, mvmeta, and glst. However, there are several cases for which these programs do not suffice. For instance, there is no software for performing univariate meta-analysis with correlated estimates, for multilevel or hierarchica...

Bayesian Analysis in Stata using WinBUGS

WinBUGS is a program for Bayesian model fitting by Gibbs sampling. WinBUGS has very limited facilities for data handling while Stata has no routines for Bayesian analysis, and as a result there is a lot to be gained by running Stata and WinBUGS in combination. A set of ado files are presented that enable data to be processed in Stata, passed to WinBUGS for model fitting and the results read bac...

Spatial panel data models using Stata

xsmle is a new command for spatial analysis using Stata. We consider the quasi-maximum likelihood estimation of a wide set of both fixedand randomeffects spatial models for balanced panel data. Of special note is that xsmle allows to handle unbalanced panels thanks to its full compatibility with the mi suite of commands, to use spatial weight matrices in the form of both Stata matrices and spma...

Measuring and assessing software test processes using test data

* This work was partially supported by the U. S. Army Research Laboratory under the contract DAKF-11-99-P-127. Abstract Testing of large-scale software systems is a complex and expensive process that involves both technical and managerial issues. To improve its cost-effectiveness, the process should be continuously monitored, consistently measured, and carefully assessed. This paper proposes an...
