The constant is insignificant

Postby Jedrek » Tue Aug 23, 2011 4:48 pm

Is it ok for a probit model that the constant or "C" is insignificant?

If in probit model I have constant (or "C") insignificant, am I allowed to exclude it from the model?
Is it fine?

How do I process with a insignificant constant when I want to get the predicted probability of a certain event? Will I use the value of the constant to calculate the predicted probability as well as all slope values along with their observed (out of sample) x values?
