Constant term P value is zero

[deepak kumar]

In my OLS regression. I am getting a p-value for constant is zero. what it signifies.i have heard it means your model is weak but I am getting R2=0.7 and after 3-SLS same thing happens p-value for constant is zero. and R2=0.67.can you explain?
Thank you

I know my two equations have endogeneity that's why I use 3-SLS.

P-value not zero; just very small. Just a matter of display rounding.

Intercept being significantly different from zero has nothing to do with the model being weak — unless your idea is that the intercept should be zero.

Thank for your suggestion nick cox. it is really helpful.I have one more problem. running 3-SLS regression. I got everything right. but endogenous variables are blank.why?it will be very helpful for my project.
Thank you

Seems like a very different new question, so please start a new thread.

hi nick...i dont have proble with const. term being zero...... my question is constant(intercept) p value being significant means p value <0.05.

[deepak kumar]

what that means... p value of constant term

It is hard to understand your question. It looks like you don't know what a p-value is in general. Is that true? I am not trying to make you look bad (if it comes down to it, most people who report p-values have trouble with its correct interpretation) I am just trying to find out at what level I should respond such that the answer is useful to you.

[deepak kumar]

i know p-value...you can respond at any level.
