Weibull Distribution Inverse CDF Calculator

Calculate the quantile for a Weibull distribution using: $$ Q(p;k,\lambda)=\lambda\left[-\ln(1-p)\right]^{\frac{1}{k}},\quad 0

* Enter a probability $ p $ ( $ 00 $ ), and scale parameter $ \lambda $ ( $ \lambda>0 $ ).

Step 1: Enter Parameters

Probability, $ p $:

e.g., 0.5 ( \( 0

Shape, $ k $:

e.g., 1.5 ( $ k>0 $ )

Scale, $ \lambda $:

e.g., 1 ( $ \lambda>0 $ )
