Alex's answer shows you a solution for standard normal distribution (mean = 0, standard deviation = 1). Heavy-Tailed Distributions 15. This is a normal distribution curve representing probability density function. The nice thing is that this target distribution only needs to be proportional to the posterior distribution, which means we dont need to evaluate the potentially intractable marginal likelihood, which is just a normalizing constant. Introduction Figure 1.1: An Ideal Normal Distribution, Photo by: Medium. What you can do is take an epsilon value, suppose 1e-6, and integrate over the area between x & x+e to calculate the pdf at a point. Removing repeating rows and columns from 2d array.
