Help me understand the quantile (inverse CDF) function
May 16, 2016 · The CDF (cumulative distribution function) is more convenient as the function plotted is increasing along the x-axis and the y-axis. Extracting the quantile, that is, the variate from CDF is …

probability - Find expected value using CDF - Cross Validated
I'm trying to solve the following problem: Let X have the CDF F(x) = 1 − x − α, x ≥ 1. Find E(X) for those values of α for which E(X) exists. How can I determine which values of α exist? What do I do with the …
calculus - How is the derivative of the CDF of a random variable $X ...
This function, $F (x)$, is called the "cumulative distribution function," or CDF. It is defined in this manner, so the relationship between CDF and PDF is not coincidental -- it is by design.
estimation - What is the proper way to estimate the CDF for a ...
My initial thought was 'I don't think there is an answer to this question.' Similar to what is written in one of the replies. The idea of a confidence interval about some smooth curve, and then getting narrower as …

Jul 19, 2010 · How can I find the PDF (probability density function) of a distribution given the CDF (cumulative distribution function)?
probability - How do I find the cumulative distribution function of a ...
How would I find the cumulative distribution function of a binomial? I know I'd have to integrate it with its given parameters but how would someone go about doing that?
distributions - Empirical CDF vs CDF - Cross Validated
Oct 13, 2016 · The CDF is a theoretical construct - it is what you would see if you could take infinitely many samples. The empirical CDF usually approximates the CDF quite well, especially for large …
