Weibull

Transform > Random Data > Weibull

 

Generates random data from a weibull distribution between two points that you designate.

The probability density function of the Weibull distribution is given by: f(x;k,a) = (k/a)*(x/a)^(k-1)*exp(-(x/a)k)

 

 

Dialog box items

Target Column:
Enter a storage column for the generated values. Leave blank to have VisualStat automatically name the target column.

Sampling:
Choose from the following options:

oSample Size: Enter the number of rows of random data you want to generate.

oDistribution: Select the distribution for the variable.

oSet Seed with: Lets you start a random number sequence with a seed you specify.

Scale : Sets the scale parameter for the distribution. The scale parameter must be positive.

Shape: Sets the shape parameter for the distribution. The shape parameter must be positive.
