Ibeta: Incomplete Beta Function

Description

Calculation of the incomplete beta function used insncFun.01110

Usage

Ibeta(z, a, b)

Arguments

z

Vector of n model parameters.

a

Vector of n model parameters.

b

Vector of n model parameters.

Value

Returns a vector of numerical values

Details

If a=1 or a=1/n and b=0, this implementation cannot evaluate values for z < 1.014.

Examples

# NOT RUN {
x = seq(.5, 4.2 , length = 20)
alf = 0.1
n = 2
y = 1 + (alf * 10^x)^n

result <- Ibeta(z = y, a = 1, b = 0 )

# }
