Step #1: Find the mean. Generating Skewed Random Numbers Using Each cost needs to be spread over a number of months in something approximating a bell curve where I can set a parameter for the skew and "flatness" of the curve. Step#2 – Now we give a parameter to the function which is alpha and beta, Step#3 – Now in the Weibull distribution box type, Step#4 – Press Tab and click on the Fx function bar, Step#5 – A dialog box appears for the function arguments, Step#6 – Now, we will give the value of the function and value of the parameters, i.e., Alpha and Beta.
