I am trying to test the impact that margin trading status has on stock liquidity. test age=age2=0. Test for equality of parameters within a model. Juni 2009 17:02 An: [email protected] Betreff: st: Testing the Equality of Coefficients Across Two xtabond Arellano-Bond Regressions Dear Statalist, I am trying to get stata to test the equality of coefficient estimates following two xtabond arellano-bond regressions. Many thanks, Sharon Re: test of the equality of coefficients in two models Aug 17, 2010; 04:07am — by Sascha Heller Maybe I don't understand your question exactly, but for the STATA example (given in the link), it work's fine when clustering for any other variable (hours etc.) I want to test if $\beta$ and $\omega$ are statistically different. 22 Jan 2019, 19:17. This is taken from Dallas survey data (original data link, survey instrument link), and they asked about fear of crime, and split up the questions between fear of property victimization and violent victimization. H. A: β. 1 = β. 1 ≠ β. Stata’s official website gives an example of the output: In this example, to test the equality of coefficients on x1 and x2, 6.06 and 2.80 are the F-stats that we are looking for. If you google "test equality of correlation coefficients stata" you'll find CORTESTI: Stata module to test equality of two correlation coefficients H. 0: β. It may be helpful to note that this is the same as testing . Using the Base Model, again test the claim that the return to each additional year of schooling is nine percent, but this time do not use Stata's test … more coefficients within a model are equal; we’ll also show how to test more complicated sorts of equality constraints. You'll increase your chances of a useful answer by following the FAQ on asking questions - provide Stata code in code delimiters, readable Stata output, and sample data using dataex. 2. H. 0: β. As promised earlier, here is one example of testing coefficient equalities in SPSS, Stata, and R.. The only differece between the equation is the dependent variables, which represents regional votes for different parties. Does that answer your question? OR We want to compare regression beta's coming from two different regressions. Test the claim that the variable age does not belong in the model. 1 - … I would normally use suest but it is not possible with reg2hdfe. > In fact, after estimating sqreg for 10 quantiles, I want to > see if the coefficient of a variable (e.g. I estimate them using the STATA command reg2hdfe with cluster at individual level. Suppose you wish to test . Herve M. Caci, 2000. "CORTESTI: Stata module to test equality of two correlation coefficients," Statistical Software Components S407302, Boston College Department of Economics, revised 07 Nov 2000.Handle: RePEc:boc:bocode:s407302 Note: This module may be installed from within Stata by typing "ssc install cortesti". Dear Stata Forum, I was trying to compare (or test the equality of) the coefficients 1. of the same specification (using 'xtreg') but for male and female samples using 'estimates store' and then 'suest' command. Then following commands will test the equality of coefficients on x1 and x2: ge g2=(group==2) regress y c.x1##i.g2 c.x2##i.g2 contrast g2 g2#c.x1 g2#c.x2, overall. If you want to test whether two estimates (whatever estimates) are equal you cannot do so by looking if the confidence intervals overlap. and the SEs change. Stata reports it has omitted all independent variables (11 in total, but 'ESG' is the variable of interest) due to collinearity (I assume that's supposed to happen) The coefficient for "which_outcome#c.ESG2" is statistically significant, but does not match the actual difference between both coefficients when I run the regressions separately. Here we have different dependent variables, but the same independent variables.
