Calculates the probability densities, cumulative probabilities, and inverse cumulative probabilities for a t distribution.
The t distribution is symmetric about zero but has tails that are more spread out than those of the normal distribution. With increasing degrees of freedom, the t distribution looks more like the normal distribution.
Enter the column you want to evaluate.
Enter a storage column for the generated values. Leave blank to have VisualStat automatically name the target column.
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.
•Deg Freedom: Enter the number of degrees of freedom you want to define the t distribution.
