Mean of a probability distribution function
WebThe distribution object display includes the parameter estimates for the mean ( mu) and standard deviation ( sigma ), and the 95% confidence intervals for the parameters. … WebIn Probability and Statistics, the Cumulative Distribution Function (CDF) of a real-valued random variable, say “X”, which is evaluated at x, is the probability that X takes a value less than or equal to the x. A random variable is a variable that defines the possible outcome values of an unexpected phenomenon.

WebA CDF function, such as F (x), is the integral of the PDF f (x) up to x. That is, the probability of getting a value x or smaller P (Y <= x) = F (x). So if you want to find the probability of rain between 1.9 < Y < 2.1 you can use F (2.1) - F (1.9), which is equal to integrating f (x) from x = 1.9 to 2.1. ( 17 votes) Show more... tarjeism
