Finding the Area Overlap Between Two Skewed Normal Distributions Using SciPy's Quad Function: A Step-by-Step Guide to Correct Implementation and Intersection Detection.
Understanding the Problem with scipy’s Quad Function and Skewnorm Distribution Overview of Skewnorm Distribution The skewnorm distribution, also known as the skewed normal distribution, is a continuous probability distribution that deviates from the standard normal distribution. It is characterized by its location parameter (loc) and scale parameter (scale). The shape of this distribution can be controlled using an additional parameter called “skewness” or “asymmetry,” which affects how the tails of the distribution are shaped.
