adding poisson distribution
adding poisson distribution & limited chi_squared distribution and goodness-of-fit test
in-progress bernoulli work
degreeking variables
dof -> degrees_of_freedom
fixing return argument and double semi-colon
a factorial function is probably of general use in a statistics library, so don't suggest it's private
expand ternaries to full if else
finish filling in the χ2 table
add leading zeros to please travis-ci
semicolons for jshint
proper indents for jshint
properly declaring i & p
replacing forEach with traditional for
fixing declaration of k, indentation of poisson return, removing stray console.log
spell out distribution_functions and be clearer about what it holds
converting frequency objects to arrays in order to remove all but one occurrence of Object.keys
Merge branch 'master' into poisson_plus_chi_squared
removing _get_random; this is for future bernoulli work
