Ibeta: Incomplete Beta Function

In spsh: Estimation and Prediction of Parameters of Various Soil Hydraulic Property Models

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.

Details

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

Value

Returns a vector of numerical values

Examples

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 )
