Comparing Distributions, Cont'd
Given two sets of data, can generalize to a single question: Are the sets drawn from the same DF?
Recall can only disprove, not prove.
May have continuous or binned data.
May want to compare one data set with known DF, or two unknown data sets with each other.
Popular technique for binned data is the 2 test. For continuous data, use the KS test. NRiC §14.3.
