Exponential Distribution

Transform > Random Data > Exponential

 

Generates random data from an exponential distribution.

Use the exponential distribution for time series data when the data are constant, such as when units have a constant failure rate. Use when random variables are greater than 0.

 

 

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.

Lambda:
Enter the lambda parameter to define the exponential distribution.
