WebOct 21, 2013 · scipy.stats.lomax¶ scipy.stats.lomax = [source] ¶ A Lomax (Pareto of the second kind) continuous random variable. Continuous random variables are defined from a standard form and may require some shape parameters to complete its specification. WebAll random variables (discrete and continuous) have a cumulative distribution function. It is a function giving the probability that the random variable $X$ is less than or equal to $x$, for every value $x$. For a discrete random variable, the cumulative distribution function is found by summing up the probabilities. openssl crt key to pem
