Package choices provides a library for simple a/b and multivariate testing. choices uses hashing to uniquely assign users to experiments and decide the values the user is assigned. This allows us to quickly assign a user to an experiment with out having to look up what they were assigned previously. Most of the ideas in this package are based off of Facebook's Planout. In choices there are three main concepts. Namespaces, Experiments, and Params. Namespaces split traffic between the experiments they contain. Experiments are the element you are testing. Experiments are made up of one or more Params. Params are a key value pair. The value can be either a Uniform Choice value or a Weighted Choice value. In most cases you will want to create one namespace per experiment. If you have experiments that might have interactions you can use namespaces to split the traffic between them. For example, if you are running a test on a banner and another test that takes over the whole page, you will want to split the traffic between these two tests. Another example, is if you want to run a test on a small percent of traffic. Namespaces contain a list of TeamID's. These TeamID's are used to deterime which Experiments to return to the caller. Experiments contain the Params for a running experiment. When a caller queries Namespaces, Namespaces will hash the user into a segment, It will then check if the segment is contained in an Experiment. If the segment is contained in the experiment then the experiment will be evaluated. An experiment will in turn evaluate each of it's Params. Params are key-value pairs. They Options for value are Uniform choice or Weighted choice. Uniform choices will be selected in a uniform fashion. Weighted choices will be selected based on the proportions supplied in the weights.
