python p value
From http://docs.scipy.org/doc/scipy/reference/tutorial/stats.html. As an exercise, we can calculate our ttest also directly without using the provided function, which should give us the same answer, and so it does: tt = (sm-m)/np.sqrt(sv/float(n)) # t-s, This is kind of overkill but let's give it a go. First lets use statsmodel to find out what the p-values should be import pandas as pd import numpy as np from sklearn import datasets, linear_model from sklearn.linear_model import LinearRegression imp
