Fix multinomial expectation and variance

@mavam mavam released this Mar 12, 2016 · 6 commits to master since this release

This release primarily fixes how expectation and variance was shown in the multinomial distribution (#14). In particular, @faridcher contributed the following changes:

  • Use matrix instead of scalar form for multinomial (b0a8912)
  • Exclude *.gz files created during compilation (3b30e26)
  • Add missing d\theta in posterior mean (af30a34)
  • Add constraint on Students't expectation (7d0082e)

This release also improves the build process on Windows (#15).

Corrected Exponential and Gamma Plots

@mavam mavam released this Feb 5, 2016 · 17 commits to master since this release

The parameters in the plots from exponential and gamma versions did not correspond to what the plots were showing. While the legend contained the scale parameter beta, the plot parameterization used the rate parameter lambda.

First release

@mavam mavam released this Oct 21, 2015 · 22 commits to master since this release

This first release represents a stable snapshot of the probability and statistics cookbook after 5 years of version control. From now on, the development switches to a variant of semantic versioning:

  • The major version changes when adding a new section or topic.
  • The minor version changes for non-trivial fixes, corrections, or improvements.
  • The patch version changes for trivial fixes, such as typos in text or formulas.

After having removed the clumsy translation infrastructure, contributing becomes hopefully easier as well.

Big thanks to all the contributors so far!
