Cluster Analysis of Heterogeneous Rank Data
... since two arbitrary partial rankings will in general contain different subsets of the items. An extensive review of rank comparisons can be found in (Critchlow, 1985). Clustering of rank data aims at the identification of groups of rankers with a common, typical preference behavior (Marden, 1995). A ...

Expectation–maximization algorithm
In statistics, an expectation–maximization (EM) algorithm is an iterative method for finding maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables. The EM iteration alternates between performing an expectation (E) step, which creates a function for the expectation of the log-likelihood evaluated using the current estimate for the parameters, and a maximization (M) step, which computes parameters maximizing the expected log-likelihood found on the E step. These parameter-estimates are then used to determine the distribution of the latent variables in the next E step.
