I have obtained some parameter estimates and corresponding t-values. How can I use the t-values to say more about the significance of these estimates? For example, if t = \hat{\beta} / s.e.(\beta), then are larger values for t better or worse? What is the estimation error? I am confused in how to interpret their values.
Can someone recommend me a website or book where this is explained?
Thanks!
PS. If in the hypothetical equation Y = aX + e the error e is normally distributed with mean zero and variance (\sigma_e)^2, does that mean that a is normally distributed as well? Because from my understanding one needs a distribution for the parameter in order to apply a significance test, right?
