[14 pdfgeo (]: Finds the probability density of specified value x for a geometric distribu-
tion.
Format: pdfgeo (success probability, value of x)
* The success probability is 0≤p≤1.
<Example 14>
Find the probability density of a geometric distribution with success probability of 5.6%
that it will be successful the 26th time.
Key operation:
F 1 4 0.056 , 26 ) ®
[15 cdfgeo (]: Finds the probability of a specified range of x for geometric distribution.
Format: cdfgeo (success probability, value of x)
<Example 15>
Find the probability for example 14 using range up to x = 26.
Key operation:
F 1 5 0.056 , 26 ) ®
Limitations for calculating the distribution function:
For the following statistical distribution functions, the range of degree of freedom in
which calculation can be made is limited to those shown below.
1) pdfT( Degrees of freedom ≤ 140
2) cdfT( Degrees of freedom ≤ 670
3) pdfχ

Degrees of freedom ≤ 141
4) pdfF( Degrees of freedom ≤ 70
5) cdfF( Degrees of freedom ≤ 670
(For both degrees of freedom to be input)
6) pdfpoi( Mean of poisson distribution ≤ 230
7) cdfgeo( Success probability is 0 ≤ p ≤ 1
