Example: BinomialPD(3,5,0.5) = 0.3125 ; BinomialPD({3,5},5,0.5) = {0.3125,0.03125}
Binomial Cumulative Dist BinomialCD(,)
Returns the binomial cumulative distribution ( p value) for the specified data.
Syntax: BinomialCD([[Lower,]Upper,] n , P )
Example: BinomialCD(5,10,0.5) = 0.623046875 ; BinomialCD({0,5},{5,8},10,0.5) =
{0.623046875,0.6123046875}
Inverse Binomial Cumulative Dist InvBinomialCD(,,)
Returns the inverse binomial cumulative distribution for the specified p value.
Syntax: InvBinomialCD( p , n , P )
Example: InvBinomialCD(0.6,10,0.5) = 5 ; InvBinomialCD({0.6,0.3},10,0.5) = {5,4}
Precautions
• When executing the Inverse Binomial Cumulative Distribution calculation, the calculator uses the
specified p value and the value that is one less than the p value minimum number of significant digits
( p ' value) to calculate minimum number of trials values. The results are assigned to variables xInv
(calculation result using p ) and *xInv (calculation result using p '). The calculator always displays
the xInv value only. However, when the xInv and *xInv values are different, the message shown
below will appear with both values.
The calculation results of Inverse Binomial Cumulative Distribution are integers. Accuracy may be
reduced when the p value has 10 or more digits. Note that even a slight difference in calculation
accuracy affects calculation results. If a warning message appears, check the displayed values.
Poisson Probability PoissonPD(,)
Returns the Poisson probability ( p value) for the specified data.
Syntax: PoissonPD( x , λ )
Example: PoissonPD(1,1.2) = 0.3614330543 ; PoissonPD({1,2},1.2) = {0.3614330543,0.2168598326}
Poisson Cumulative Dist PoissonCD(,)
Returns the Poisson cumulative distribution ( p value) for the specified data.
Syntax: PoissonCD([Lower,]Upper, λ )
• If Lower is omitted, Lower = 0 is assumed.
Example: PoissonCD(1,2,1.2) = 0.5782928869 ; PoissonCD({1,1},{2,3},1.2) = {0.5782928869,0.6650368199}
Inverse Poisson Cumul Dist InvPoissonCD(,)
Returns the inverse Poisson cumulative distribution for the specified p value.
Syntax: InvPoissonCD( p , λ )
Example: InvPoissonCD(0.58,1.2) = 1 ; InvPoissonCD({0.58,0.75},1.2) = {1,2}
Precautions are the same as those for
Geometric Probability GeoPD(,)
Returns the geometric probability ( p value) for the specified data.
Syntax: GeoPD( x , P )
