It’s not possible to estimate the parameters of a Weibull distribution using the Inductive Statistics option. With this option you can calculate the Weibull distribution or density function using the Distribution Analysis Object.
But you could use the Non-Linear Curve Fit Analysis Object to estimate the parameters. Here it’s possible to create your own user-defined function (Example: Weibul density function):
Dim a = p[0]
Dim b = p[1]
a * b *x^(b-1)*E^(-a*x^b)
With the analysis object you can estimate the parameters a and b.
The algorithm is is based on the Newton method of least squares.
