WBLIN
This function evaluates the inverse of the Weibull cumulative distribution function.
Function Return Value
WBLIN — Function value, the value of the inverse of the Weibull cumulative distribution function. (Output)
Required Arguments
P — Probability for which the inverse of the Weibull cumulative distribution function is to be evaluated. (Input)
A — Scale parameter. (Input)
B — Shape parameter. (Input)
FORTRAN 90 Interface
Generic: WBLIN (P, A, B)
Specific: The specific interface names are S_WBLIN and D_WBLIN.
FORTRAN 77 Interface
Single: WBLIN (P, A, B)
Double: The double precision name is DWBLIN.
Description
The function WBLIN evaluates the inverse distribution function of a Weibull random variable with scale parameter A and shape parameter B.
Example
In this example, we evaluate the inverse probability function at P = 0.8946, A = 1.0, B = 2.0.
USE UMACH_INT
USE WBLIN_INT
IMPLICIT NONE
INTEGER NOUT
REAL X, A, B, P
CALL UMACH(2, NOUT)
P = 0.8946
A = 1.0
B = 2.0
X = WBLIN(P, A, B)
WRITE (NOUT, 99999) P, A, B, X
99999 FORMAT (' WBLIN(', F4.2, ', ', F4.2, ', ', F4.2, ') = ', F6.4)
END
Output
WBLIN(0.8946, 1.00, 2.00) = 1.5000
