AuthorPaul Lin, StataCorp The variance–covariance matrix and coefficient vector are available to you after any estimation command as e(V) and e(b). You can use them directly, or you can place them in a matrix of your choosing.
Stata has a friendly dialog box that can assist you in building multilevel models. If you would like a brief introduction using the GUI, you can watch a demonstration on Stata’s YouTube Channel: Introduction to multilevel linear models in Stata, part 1: Thextmixedcommand Multilevel data Mul...
TitleStata 7: Obtaining the correct variance–covariance matrix from the bs routine AuthorAllen McDowell, StataCorp Question If I run matrix myV=e(V) after running thebscommand, the matrix that is saved is not the variance–covariance matrix for my model (i.e., the diagonal of this matrix...
The methodological developments presented are implemented in a new Stata command named xtci, and an expanded version of the present article is published on the Stata Journal (Bottai and Orsini, 2004). The random-effects linear model has been widely applied to ...
I describe a command that simultaneously solves the extended es- timating equations estimator for parameters in the link and variance functions along with ... A Basu - 《Stata Journal》 被引量: 78发表: 2005年 Performance of Confidence Intervals in Regression Models with Unbalanced One-Fold Nested...
Rather than using the oneway command,we could have performed this analysis by using anova.Example 1 in[R] anova repeats this same analysis.You may wish to compare the output. You will,nd the oneway command quicker than the anova command( and) as you will learn,oneway allows you to perf...
To estimate this same model using RVE, the robu command can be adapted as follows: robu(formula = g ~ -1 + O1 + O2 + O3, data = DATA1, studynum = StudyID, var.eff.size = v, small = TRUE). Note that as with the SAS code, we include the three dummy-coded indicators and “...
MixWILD Software Overview The MixWILD software is used to assist users in adding model parameters and displaying output of the analysis without relying on a command-line interface. It allows users to select the data file to process, assign missing value codes, add or remove regressors from ...
In fact, Joe Hilbe requested this very idea when we were writing theglmcommand for Stata 7. I liked the idea, but in the rush of getting everything together, I let the idea slide, as I never got around to discussing it with StataCorp. I was concerned over the possible implications for...
