Chapter 10: Statistics & Regression Calculations 10 pdfbin( pdfbin(trial number, success probability [, success number])) Finds the probability density of a specified value x for the binomial distribution. A list cannot be used except for success numbers. When the success number is not specified, the calculation is executed by entering values from 0 to the trial number and displays the list. Limitations: Success probability is 0 ≤ p ≤ 1. Example Find the probability density for 15 trials with x = 7, for the binomial distribution with success probability of 30%. 11 cdfbin( cdfbin(trial number, success probability [, success number])) Finds the probability of a specified range x for the binomial distribution. A list cannot be used except for success numbers. When the success number is not specified, the calculation is executed by entering values from 0 to the trial number and displays the list. Example Find the probability of range up to x = 7 for the F distribution generated with degrees of freedom 15 and 10. 12 pdfpoi( pdfpoi(mean, value) Finds the probability density of a specified value x for a Poisson distribution of mean µ. Limitations: Mean of Poisson distribution ≤ 230 Example Find the probability density of x = 4, for the mean of a Poisson distribution of 3.6. 181
