weibplot

Weibull probability plot

Syntax

• weibplot(X)
  h = weibplot(X)
  

Description

weibplot(X) displays a Weibull probability plot of the data in X. If X is a matrix, weibplot displays a plot for each column.

h = weibplot(X) returns handles to the plotted lines.

The purpose of a Weibull probability plot is to graphically assess whether the data in X could come from a Weibull distribution. If the data are Weibull the plot will be linear. Other distribution types may introduce curvature in the plot.

Example

• r = weibrnd(1.2,1.5,50,1);
  weibplot(r)
