Cdf of a distribution
WebThe NORM.DIST function returns values for the normal probability density function (PDF) and the normal cumulative distribution function (CDF). For example, NORM.DIST (5,3,2,TRUE) returns the output 0.841 which corresponds to the area to the left of 5 under the bell-shaped curve described by a mean of 3 and a standard deviation of 2. WebOct 13, 2016 · The cumulative distribution function F ( x) gives the P ( X ≤ x). An empirical cumulative distribution function function G ( x) gives P ( X ≤ x) based on the observations in your sample. The distinction is which probability measure is used. For the empirical CDF, you use the probability measure defined by the frequency counts in an ...
