2. STATA FILES You can import stata files to R via foreign package through the following command. # Activate the `foreign` library library(foreign) # Read Stata data into R mydata <- read.dta("") 3. SYSTAT FILES You can import Systat files to R via foreign package through the fol...
of the estimators of interest, offering Stata-based examples along the way. Next it shows how to apply these estimators with xtabond2. It also explains how to perform the Arellano-Bond test for autocorrelation in a panel after other Stata commands, using abar. The paper ends with some ti...
We can use contrast to obtain tests of the main and interaction effects. We have statistical evidence for an interaction effect, but at this point, we can’t say much about where differences exist. A plot allows us to visualize the interaction. We can test specific hypotheses about the ...
In STATA, Bartlett’s is added onto ANOVA. The basic syntax of the command isoneway dv ivwhereivis acategorical variable. For more on running the test in STATA, seethis Notre Dame article. If youreallywant to run Bartlett’s test by hand, follow these steps [2]. ...
No. Seehttp://ideas.repec.org/a/tsj/stataj/v8y2008i3p401-412.htmlfor details. You are redefining the matrix TEST 100 times, notcreating 100 matrices. To do the latter it is most helpful to usepointers. Kit Kit Baum, Boston College Economics and DIW Berlinhttp://ideas.repec.org/e/...
(seemingly unrelated estimations), and afterwards I could test "test var1=var2=var3=var4" But now I would like to do the same thing after estimating IV (ivreg2). it shouldn't be so hard but I cannot figure out how to store the estimation results properly so that STATA can compare ...
However, it is not a difficult task, and Stata provides all the tools you need to do this.In the section, Test Procedure in Stata, we illustrate the Stata procedure required to perform a binomial logistic regression assuming that no assumptions have been violated. First, we set out the ...
