From Data to Probability
In statistics, the P Value is a fundamental concept that plays a crucial role in hypothesis testing. It quantifies the probability of observing a test statistic at least as extreme as the one observed, assuming the null hypothesis is true. Essentially, the P Value helps us assess whether the obse...
Kullback-Leibler and Wasserstein Distances
In mathematics, the concept of “distance” extends beyond the everyday understanding of the term. Typically, when we think of distance, we envision Euclidean distance, which is the straight-line distance between two points in space. This form of distance is familiar and intuitive, often represente...
