Definition of a p-value. How to use a p-value in a hypothesis test. Find the value on a TI 83 calculator. Hundreds of how-tos for stats.
The p-value(which should be smaller than the critical value of the F statistic in order to have a significant test) is normally the area beneath the right tail of the f distribution at the F-value, if I understood the concept correctly. With respect to the reg...
Unless your goal is to somehow improve on what is already written, or you simply don't have those existing tools, then you should never be reinventing the wheel. Use existing code, for example, regress is in the stats toolbox. Or you could even use my polyfitn f...

P-values can be calculated from a cumulative distribution (norm.cdf()fromscipy.stats) which represents the probability of obtaining a value equal to orless thanthe one observed. Then to calculate the p-value we calculate1 - norm.cdf()to find the probabilitygreater thanthe one observed:...
