Fit_transform but no transform() #11

Closed M-Harrington closed 3 years ago

M-Harrington commented 3 years ago

Hi, maybe I've missed it, but could you add a transform method to supplement fit_transform? Ideally I'd like to call this on new data after it's already been fit and return PCs without refitting.

The fitted model is stored in results and with the model it is possible to do the transformation step. However, I agree that it may be a bit inconvenient. So I created a transform function!

pip install -U distfit
import distfit
print(distfit.__version__)

The version should be >= 1.4.0

An example can be found in the readme!

Thank you for the resource, and thank you for authoring the package! It’s great and has a lot more useful functionality than the sole arm package!

Cheers
