Document Summary

Stor 155: introduction to statistics lecture 6: erlang distribution (1/27/15) = rate of individual arrivals in the poisson process: w = number of occurrences/arrivals that you await, fixed number. Mode: to calculate the mode for an erlang distribution, use the following formula, m = (w 1) / . If w increases, the mode increases as well: distribution will become more symmetrical. Density function: to calculate the height of the density function, use the following formula, f(x) = ( w e- cxw-1) / (w-1!)
