The logistic distribution is continuous. It is commonly used to describe growth (the size of a population expressed as a function of a time variable). It can also be used to describe chemical reactions and the course of growth for a population or individual.
The mean parameter is the average value, which for this distribution is the same as the mode, since this is a symmetrical distribution. After you select the mean parameter, you can estimate the scale parameter. The scale parameter is a number greater than 0. The larger the scale parameter, the greater the variance. |
