Webb) The problem is that the formula for the minimum required sample size is n = z 2 ⋅ p ⋅ ( 1 − p) d 2 where z = z α / 2 and d is half the length of the corresponding confidence interval. So in order to determine n you need to know the true value of … WebJan 13, 2015 · p_values = [2* (1-stats.t.cdf (np.abs (i), (len (newX)-1))) for i in ts_b], the t-values follows a chi-squared distribution of degree len (newX)-1 instead of following a chi-squared distribution of degree len (newX)-len (newX.columns)-1. So this should be: p_values = [2* (1-stats.t.cdf (np.abs (i), (len (newX)-len (newX.columns)-1))) for i in ts_b] WebMar 10, 2024 · The p-value is a probability measure and uses the degree of freedom and estimation based on the alpha value of a t-test.
