Thanks for explaining. I'm, unfortunately, not the right person for this question. I was merely suggesting a function I had come across in the docs. WebbThe optimization problem involves estimating the posterior probability for each candidate hypothesis. We can determine the MAP hypotheses by using Bayes theorem to calculate the posterior probability of each candidate hypothesis. — Page 157, Machine Learning, 1997. Like MLE, solving the optimization problem depends on the choice of model.

Then we will subtract the smaller value from the larger value: 0.8413 – 0.6554 = 0.1859. Thus, the probability that a value in a given distribution has a z-score between z = 0.4 and z = 1 is approximately 0.1859. python t2sdk
