What is the differences between correlation and collinearity?

How can i define labels that shows for each plot in the graph the specific value?

Hello,
Which option Huber-White or GLM is " better" in the case of Poisson model with robust standard errors?

And should i use robust standard errors if im estimating with negative binomial as well?

This is the result i just got after doing : a. astimate the variables by the Poisson-Count regression model, b. forecast and named the forecasted variable as " patentffinal", c. using the command :
equation testeq.ls (patent-patentffinal)^2-patent patentffinal^2.

Is it o.k?

Hi, The first variable is the fit variable which i got by using the command: fit patentfittct . the second variable i got by "forecast". Doesnt fit has the same meaning as forecast?! It is really confusing because at the manual it written , and i quote :"first estimate the Poisson and...

I did both test that are mentioned in the manual Cameron and Trivedi and Wooldridge - is it reasonable that i got underdispersion at the first test and overdispersion at the last test?
Im really confused.

Does Eviews have the possibility to perform a Fixed effect/Random effect estimation when i'm choosing Poisson-count model?

How can i know what is the significant level of the value from the pearson chi square test?

Does Eviews have the possibility to perform a fixed effect estimation when i'm choosing Poisson-count model?

Hello,
When i'm doing a Poisson regression model and using robust standard error my explanatory variable becoming insignificant,what should i do?

I have obtained a resultes for the coefficient of : -0.008725 and its statistically significant. Is this result value implies of equidispersion or underdispersion?

Hello, I would be glad for explanation between the differences of the fitted values of the dependent variable and the forecast values. Because when i'm doing the procedure that is mentioned in page 293 at the Eviews manual and comparing the values i see that they identical. Is it always supposed to ...

Hello, I'm running a poisson regression and I would like to check the goodness of fit. My dependant variable is the number of patent application per year per firm. I have several question: Is the LR statistic is a good indication for goodness of fit ? How do i check if i have overdispersion? Finally...

Hello, Im doing a research on 3 pharmaceuticals companies and their ability to innovate (by patents) in strategic alliances with other firms. My research is focusing in the last 22 to years. When im trying to do heteroskedasticity test , i dont have that option and from reading in your forum i under...

Hello, I am performing linear regression analysis in Eviews and half of my variables are unfortunately with p.value larger than 0.05 , even though i dropped out one variable after detecting a multicollinearity it still doesnt change the p.value of the other variables. My research dealing with the ef...
