Mean of log logistic distribution
WebThe log-logistic cumulative distribution function has a simple closed form, which becomes important computationally when fitting data with censoring. For the censored observations one needs the survival function, which is the complement of the cumulative distribution function, i.e. one needs to be able to evaluate S ( t θ ) = 1 − F ( t ... WebSep 30, 2024 · The logistic of the mean of the normal distribution is not necessarily the mean of the logit-normal corresponding to it. First you'll notice we get a really interesting difference between the way these two distribution appear now.
