WebThe cumulative distribution function (CDF), as a function of x, is the integral of the PDF from -infinity to x, and therefore CDF (x) = P (-infinity < X < x).

WebJul 21, 2024 · As to graphic fitting, the literature appears to uniformly only use the CDF. Now that I understand your question, the answer is I do believe you will end up with different estimates by using the pdf over the cdf because of your choice of criteria. WebI think it's just saying that if the cdf's are the same then the pdf's are the same. PDF's don't always exist in advanced probability. Do you seriously prove that?
