Webb21 juni 2024 · Q-Q plot is often called quantile plot. It is a 2D plot in which we compare the theoretical quantiles of a distribution with the sample quantiles of a dataset. If the dataset has been generated from that distribution, we expect this chart to be close to a 45-degree line, because the sample quantiles will be similar to the theoretical quantiles.
