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.
