Weibull Distribution CDF Calculator

Calculate the cumulative distribution function (CDF) for a Weibull distribution: $$ F(x;k,\lambda)=1-e^{-(x/\lambda)^k},\quad x\ge0. $$

* Enter the value $ x $ (with $ x\ge0 $), shape parameter $ k $ ( $ k>0 $ ), and scale parameter $ \lambda $ ( $ \lambda>0 $ ).

Step 1: Enter Parameters

$ x $:

Enter a value ( $ x\ge0 $ )

Shape, $ k $:

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

Scale, $ \lambda $:

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