Hi Guys I’m trying to reproduce two papers for my dissertation, the papers ran individual regressions for each of the independent variables, then combined the all the individually significant independent variables in a final regression. Both paper then checked for multicollinearity using a correlati...

ok thanks again

ok but is c(1) = c(2) = c(3) = c(4) the correct thing to enter into the wald test to test are the coefficents significantly different from each other? will check out how to interpret results when im in college and have accesss to the help manual.

Hi guys

Is there anyway to show how much each independent variable contributes to the overall regression r-squared?

Thanks

thanks again startz, i can forget about the first part then. Is the correct way to test whether the coefficents of the dummy variables are significantly different from each other using a wald test c(1) = c(2) = c(3) = c(4)? is so how would I interpret an F-stat of .21? I have attached a the wald tes...

Hi I posted a question a while ago about testing whether the coeffiects of a number of dummy variables follow a certain order, i.e c1 > c2 > c3, and the answer I got was to perform a one sided t test. I am at the stage now where I need to perform the test and am wondering now to perform it on eviews...

Hi guys Im having a problem with a variable. My sample is 400 companies and one of my explanotory variables is the interest coverage ratio (ic) which is the companies profit divided by the interest it pays (profit/interest). The problem is that some companies dont pay any interest so that variables ...

thanks for second answer in two days startz, anyone have an opinion on using Hot deck imputation when <4% of observations are missing? would this have any major negative impacts?

Hello (accidentally posted this in the econometrics discussions forum so sorry about repost) I have a sample of 500 firms with around 50 explanatory variables. Out of the around 30000 observations there are 2000 N/A's. When I run the regression the sample size is reduced by any firm with has an N/A ...

thanks, will try later

Hi Guys

Is there anyway to test whether the coefficent of one independent variables is greater than another?

i.e c(2)>C(3)>C(4)

obviously I could just look at them to see, but is there anyway to test this.

Thanks

Rob

ok great, thanks for your help

Hi Guy Does anyone know how I would enter 2 dummy variables? I want to use a dummy for a companys industry and one for it level of multinationality. Im able to use the @expand function for one ok and and can do both at the same time e.g @expand(ind,class) but I cant do to seperate @expand with out g...
