In reality, the data is rarely perfectly Gaussian, but it will have a Gaussian-like distribution. If the sample size is large enough, we treat it as Gaussian.

What is a normal distribution? - Stats and R

WebbA Gaussian distribution, also referred to as a normal distribution, is a type of continuous probability distribution that is symmetrical about its mean; most observations cluster around the mean, and the further away an observation is from the mean, the lower its probability of occurring. Webb27 maj 2024 · Third, as @KSSV has mentioned, you can use a power transform (e.g. the Box-Cox transform that they mentioned). My understanding is that these transforms won't necessarily make the distribution strictly normal -- just more "normal-like".

WebbIt’s also possible to visualize the distribution of a categorical variable using the logic of a histogram. Discrete bins are automatically set for categorical variables, but it may also be helpful to “shrink” the bars slightly to emphasize the categorical nature of the axis: sns.displot(tips, x="day", shrink=.8) WebbTo try this approach, convert the histogram to a set of points (x,y), where x is a bin center and y is a bin height, and then fit a curve to those points. counts = histcounts (life,binEdges); binCtrs = binEdges (1:end-1) + binWidth/2; h.FaceColor = [.9 .9 .9]; hold on plot (binCtrs,counts, 'o' ); hold off
