## Hierarchical Cluster Analysis

With the distance matrix found in previous tutorial, we can use various techniques of cluster analysis for relationship discovery. For example, in the data set mtcars, we can run the distance matrix with hclust, and plot a dendrogram that displays a hierarchical relationship among the vehicles.

## Logistic Regression

We use the logistic regression equation to predict the probability of a
dependent variable taking the dichotomy values 0 or 1. Suppose x_{1}, x_{2},
..., x_{p} are the independent variables, α and β_{k} (k = 1, 2, ..., p) are the
parameters, and E(y) is the expected value of the dependent variable y, then the
logistic regression equation is:
