A scipy-like implementation of the PERT distribution
A scipy-like implementation of the PERT distribution.
In my current job I work a fair amount with the PERT (also known as Beta-PERT) distribution, but there's currently no implementation of this in scipy. To make up the deficency I crafted up my own PERT distribution class, leveraging numpy and scipy to properly flesh out the functionality. The API is heavily modeled after the scipy.stats methods API's.
TODO: when I figure out how in blazes to add these ;-)
Installation is straightforward:
pip install pertdist
Usage is very similar to what you would find in a scipy.stats class as well:
from pert import PERT import seaborn as sns pert = PERT(10, 190, 200) sns.kdeplot(pert.rvs(10000))
On running this you should see a chart of a heavily low/left skewed distribution (recommended running in Jupyter or Spyder).
- Develop unit tests
- Especially around flexible identification of various data types, eg: accepting DataFrames, Series, lists, etc.
- Build out the following scipy function analogues:
- stats (implemented, but needs refinement)
