P ( Y = 1 x) = f ( x Y = 1) ⋅ P ( Y = 1) f ( x) where f denotes the probability densities, which are estimated by a kernel density estimator from the data. Webb26 apr. 2024 · Probability plots might be the best way to determine whether your data follow a particular distribution. If your data follow the straight line on the graph, the distribution fits your data. This process is simple to do visually. Informally, this process is called the “fat pencil” test. free-codecs.com
