ESTIMATING MODE INVARIANT ATTRIBUTES

[Swalha Salim]

Hello, 

I have two questions. 

1. In my estimation some of the coefficients are not statistically significant. If I want to estimate the coefficients at different significance level, how do I go about it?

2. I want to introduce 3 more variables in my model that are mode invariant (socio-economic variables). Two are dummy coded and one is continuous. Please assist me how to do this.

Thank you.

Maliha.
