Webb21 juni 2024 · The sample quantiles are very similar to the theoretical quantiles (i.e. the blue points are close to the red line). There are some outliers that make some noise at the lower and upper bounds of this chart, but it’s not a huge problem, because the greatest part of the sample distribution fits quite well with the theoretical one. Webb25 nov. 2024 · When we compare a sample with a theoretical distribution, we can use a Monte Carlo simulation to create a test statistics distribution. For instance, if we want to …

WebbIn statistics, an empirical distribution function (commonly also called an empirical Cumulative Distribution Function, eCDF) is the distribution function associated with the empirical measure of a sample. This cumulative distribution function is a step function that jumps up by 1/n at each of the n data points. Its value at any specified value of the …
