Week 9-GSoC 2020
This blogs describes the week 9, the beginning week of the final phase. This week, I continued to work on the extension of Compound Distributions as well as completing the Matrix Distributions. Some of the highlights of this week are:
Open PRs:
- Change return type of
PandEwith evaluate=False- This PR aims at changing the return type of
P,Eanddensitywithevaluate=False. Currently, they return unevaluatedIntegralorSumbut this needs be changed to return their respective symbolic classes.
- This PR aims at changing the return type of
- Allowing more than one RV in Compound Distributions
- This PR is an extension of PR#19648 to change the marginalisation algorithm and handle more than one random variables in Compound Distributions.
- Added Wishart and MatrixNormal Distributions
- This PR was completed last week but was stalled because SymPy didn’t have any
Setclass to represent the set of matrices. However, I opened a new PR which added the requiredSetand this is now ready for merging.
- This PR was completed last week but was stalled because SymPy didn’t have any
Merged PRs:
- Added MatrixSet
- This PR added a new set class to represent the set of matrices over a given set. This was added as a result of PR#19795
