Week 7

This blog describes the 7^th week of the program and the 3^rd week of Phase 2. Some of the key highlights on the discussions and the implementations during this week are:

Discussions

• Matrix Distributions

  • This issues contains the discussions for adding the matrix distributions which are not possible to implement along with the joint distributions.

Open PRs

• MatrixGamma Distribution

  • This is a prototype PR for showing the Matrix Distribution additions. However, this needs to be changed and will be implemented in a new file as suggested by Gagandeep Singh.

• Add symbolic Moment and CentralMoment

  • This PR fixes one of the old issue for adding symbolic classes for Moment and CentralMoment. This PR also links moment with Moment.doit() and cmoment with CentralMoment.doit().

Merged PRs

• Compound Distributions

  • Adding support for Compound Distributions was one of the main aim of the project as well as of the Phase 2 as it was stalled from 2018. It now has its own Probability Space and is implemented in a new file which was previously mixed up with Joint Rvs.

• Add doit in symbolic Probability

  • This PR adds doit method in symbolic Probability. This also links P or probability with Probability.doit(). Hence, this forms the uniformity with P linked to Probability.doit() and E linked to Expectation.doit().
