Packages

In R, there are several packages available that provide the programmer with the regression functionality. We will be using the following packages in the examples:

  • chemometrics: This package has tools to analyze chemometric data (multivariate)
  • MASS: This package offers modern applied statistics with S

Simple regression

In simple regression, we try to determine whether there is a relationship between two variables. It is assumed that there is a high degree of correlation between the two variables chosen for use in regression.

For this section, we will be using the iris dataset. The iris dataset has observations of the different characteristics of iris plants. For regression, we are seeing if there is a relationship between one characteristic of iris plants and others. As mentioned, the characteristics tested will have a high degree of correlation. The iris dataset is as follows:

> data <- read.csv("http://archive.ics.uci.edu/ml/machine-learning-databases/iris/iris.data&quot...
