WebYou can't use the builtin weibull distribution available in R, because it's a two parameters weibull distribution. You have to compute custom probability density function (3 parameters) and use it instead. – dickoa Aug 5, 2012 at 16:17 Add a comment 2 Answers Sorted by: 8 First, you might want to look at FAdist package. WebAug 16, 2024 · The least-square fit of the line gives the shape and scale parameter of the Weibull distribution considering the location parameter to be 0. The Weibull distribution also has the property that a scale parameter passes 63.2% points irrespective of the value of the shape parameter. In this plot, we draw a horizontal line at 63.2% of the y-axis.
