Calculates probabilities, cumulative probabilities, and inverse cumulative probabilities for a negative binomial distribution.
In general, the negative binomial functions accept an argument that is the probability of success p, a number of trials n, and the count of interest k, which is the number of failures that precede the ith success.
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.
•Num of trials: Enter number of trials you want to define the negative binomial distribution.
•Prob of success: Enter number between 0 and 1 for the probability of success, which will be used to define the negative binomial distribution.
