Re: Simple mean test by category

I'm not sure either we are on the same page. A simple hypothesis test allows me to test whether the mean of the entire population is equal to, say, zero - t stats with probability is produced in this test. But what if I need to perform the same mean test for 25 sub samples from this population - sep...

Re: Simple mean test by category

That's right but then how can I test that each of those 25 monthly means is statistically different from zero? My original question was more about how to perform a simple mean equality test for each month...

Re: Phillips-Ouliaris test for cointegration

Thank you for helping with the test. So, in case the first line of the output rejects the null and the second line of the output does not reject the null, how shall I interpret the results? Shall I say, series are not cointegrated? Or shall I say, one series lead the relationship and the other serie...

Re: Test of difference in R-squared

Hello again

I realized i might need to perform the Cramer's test, since I estimate the same model but for two different samples. Does anyone know how to model the Cramer's stats in Eviews? Thanks a lot.

Test of difference in R-squared

Hello guys, I am estimating two regressions, for which independent and dependent variables are the same, except for the sample compositions and the time periods are different. Is there any way I could perform test of difference in adjusted R-squared for such regressions? Either manually or in Eviews...
