WebIssue 10, December 2001. Reliability Basics: Rank Regression Parameter Estimation. In the last two editions of Reliability Basics, we looked at the probability plotting and maximum likelihood methods of parameter estimation. In this edition, we will examine the rank regression method for parameter estimation, also known as the least squares method. WebIn data mining and statistics, hierarchical clustering (also called hierarchical cluster analysis or HCA) is a method of cluster analysis that seeks to build a hierarchy of clusters. Strategies for hierarchical clustering generally fall into two categories: Agglomerative: This is a "bottom-up" approach: Each observation starts in its own cluster, and pairs of …
