T score in python
WebThe t-score is calculated similarly to the z-score, but using sample values instead of population values. When the control sample is the same size as the treated sample, the t … WebTo get the same results, change two things: Change the estimation of the variance such that the divisor is N-1. Calculate the p-value using the cdf, that is the probability of getting a more extreme value, here using that the t-distribution is symmetric around zero. Note that the function you're comparing with does a two-sided test, and ...
