Authorities differ on how high the VIF has to be to constitute a problem. The VIF has a lower bound of 1 but no upper bound. Thus, a VIF of 1.8 tells us that the variance (the square of the standard error) of a particular coefficient is 80% larger than it would be if that predictor was completely uncorrelated with all the other predictors. ItвЂ™s called the variance inflation factor because it estimates how much the variance of a coefficient is вЂњinflatedвЂќ because of linear dependence with other predictors.

LEARN MORE IN A SEMINAR WITH PAUL ALLISON The VIF may be calculated for each predictor by doing a linear regression of that predictor on all the other predictors, and then obtaining the R 2 from that regression. But many do not realize that there are several situations in which multicollinearity can be safely ignored.Д«efore examining those situations, letвЂ™s first consider the most widely-used diagnostic for multicollinearity, the variance inflation factor (VIF). Most data analysts know that multicollinearity is not a good thing. It occurs when there are high correlations among predictor variables, leading to unreliable and unstable estimates of regression coefficients. Multicollinearity is a common problem when estimating linear or generalized linear models, including logistic regression and Cox regression.

This will make a structural break variable. Here we make a new vairable named as dum and write zeros вЂњ0вЂќ uptil 2002 and write ones вЂњ1вЂќ from 2003 and onward In sequential it has provided the three break dates in the order of their significance, as we usually use one break in the model so we take 2003 as a break.

It will tests up to 5 breaks in the data and show you the significant ones

There are 5 methods but go with the first one Now go in the stability test you have multiple break-point test To find the structural break you have to estimate AR(1) model in this the independent variable in the lag of dependent variable Following illustration is only available in eviews 8 and onward, you can get demo version of eviews from eviews website. This is the blog post to show how an unknown structural break can be found for any variable.
