For my dataset, I am trying to: Find the best fitting distribution (ex: normal, exponential, lognormal, weibull…) of a certain column, and output its parameters (and maybe visualize). Draw/pick random points from the best fitting distribution using parameters from step 1. Example dataset: “` ID | Score_1 | Number_2 1 19298 889 2 14067 600 ..
