2. Descriptive Statistics

A descriptive analysis of a given data set is typically the first part of statistical modeling and evaluation of data. In the following, we will show how the functions that come with XploRe can be used for this purpose.

All routines for descriptive analysis that we present are
part of the libraries
`xplore`
(basic routines) and
`stats`
(basic statistical
methods). We will not use graphical methods here. Tools
for the graphical exploration of data are extensively discussed in
Chapter 3.

Before proceeding to the next section, please type

library("xplore") library("stats")to load the libraries
