WebJun 22, 2024 · Cumulative Distribution A more transparent representation of the two distribution is their cumulative distribution function. At each point of the x axis ( income) we plot the percentage of data points that have an equal or lower value. The main advantages of the cumulative distribution function are that Weblognorm takes s as a shape parameter for s. The probability density above is defined in the “standardized” form. To shift and/or scale the distribution use the loc and scale parameters. Specifically, lognorm.pdf (x, s, loc, scale) is identically equivalent to lognorm.pdf (y, s) / scale with y = (x - loc) / scale.
