For ten points, identify this type of statistical data exempli ed by blood type or country of origin which can only take on one of a  xed set of values.
The Dirichlet distribution is the conjugate prior for the distribution named for this kind of data, and the probit regression technique is used for a subset of this kind of data. The techniques of dummy coding, e ects coding, and contrast coding are used to analyze this kind of data, which is described by distributions also termed generalized   Bernoulli distributions. This kind of data is termed dichotomous if it has only two possible values. The act of treating continuous data as if it were this kind of data is called discretization.
