### Transform > Random Data > Lognormal

Generates random data from a lognormal distribution.

The lognormal distribution is often used for reliability analysis and in financial applications, such as modeling stock behavior. A random variable follows the lognormal distribution if the logarithm of the random variable is normally distributed. 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.

•Mean:

Enter the mean value you want to use as the center point for the lognormal distribution.

•Variance:

Enter the variance you want to define the lognormal distribution.
