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.
