### Transform > Probability Distributions > Beta

Calculates the probability densities, cumulative probabilities, and inverse cumulative probabilities for a beta distribution.

The beta distribution is often used to model the distribution of order statistics. Use for random variables between 0 and 1.

### Dialog box items

•Source Column:

Enter the column you want to evaluate.

•Target Column:

•Statistics:

Choose from the following options:

oProbability density: Choose to calculate the probability densities.

oCumulative probability: Choose to compute the cumulative probabilities.

oInverse cumulative probability: Choose to compute the inverse of the cumulative probabilities.

•Distribution: Select the distribution for the variable.

•Alpha: Enter a number for the alpha shape parameter you want to define the beta distribution

•Beta: Enter a number for the beta shape parameter you want to define the beta distribution
