3.5.3.3.18 Wblinv
Definition:
\(xp = w b l i n v (p, a, b)\) computes the inverse Weibull cumulative distribution function for the given probability using the parameters a and b.
The inverse of the Weibull cdf is
\[x_p=[aln(\frac 1{1-p}]^{(\frac 1b)}I_{[0,1]}(p)\]
Parameters:
- \(p\) (input, double)
- The probability,0 < p < 1.
- \(a\) (input, double)
- The scale parameter, a, of the required Weibull distribution, must be positive(a > 0.0).
- \(b\) (input, double)
- The shape parameter, b, of the required Weibull distribution, must be positive (b > 0.0).
- \(xp\) (output, double)
- The value of the variate,\(x_p\)
