Some Statistical Considerations In Clustering With Binary Data
Abstract:
A statistical theory of cluster homogeneity is developed for object:, scored on binary (0,l) variables. The theory utilizes two test statistics originally suggested by Tryon and Bailey (1970). The exact sampling distribution of the statistic H2,,, "squared homogeneity for cluster g on variable r" is derived under the assumption of a random assortment of 0's and 1's in the observed clusters. Formulas for the mean and variance of H,2, "the overall homogeneity for cluster g across all variables" are derived which may be used in con- junction with probability inequalities to carry out significance tests on this statistic. Comments concerning a framework for deriving metric distances between objects scored only on binary variables are also included.

Cluster Sampling Method
To choose a cluster sample, divide the population into clusters (groups) and then randomly select some of the clusters. All the members from these clusters are in the cluster sample. For example, if you randomly sample four departments from your...
Binomial Probability Distribution
The outcomes of a binomial experiment fit a binomial probability distribution. A statistical experiment can be classified as a binomial experiment if the following conditions are met:
There are a fixed number of trials. Think of trials as repetitions of an experiment. The letter n denotes the number of trials.
There are only two possible outcomes,...

Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...
