What is python equivalent of qweibull in MathCAD?

I want to get the x value for the given quantile while the data is weibull distributed. Mathcad has qweibull and scipy has scipy.stats.norm.ppf(q) for normal distribution.

However, I dont find scipy.stats.weibull.ppf(q, c)

How can I achieve this?

Solution

  • I believe the matching function in SciPy is called scipy.stats.weibull_min and it implements the scipy.stats.weibull_min.ppf(q, c) as well.

    Formula from MathCad docs:

    Mathcad Weibull function

    Formula from SciPy docs:

    SciPy Weibull function
