Univariate

Univariate statistics implement methods for the following data types:

• Vector

• Array of Double values

• Collection which implements IEnumerable<Double> interface

  Exposes the enumerator, which supports a simple iteration over a non-generic collection.

  Examples: List<Double>, SortedList<Double>, ArrayList<Double>

• Collection which implements IEnumerable<Nullable<Double>> interface

  Exposes the enumerator, which supports a simple iteration over a collection of a nullable double type.

  Examples: List<Nullable<Double>>, SortedList<Nullable<Double>>, ArrayList<Nullable<Double>>

In matrix (two-dimensional) case columns correspond to variables and rows correspond to observations, therefore in one-dimensional case we consider one variable observations. That is why this section of Discriptive Statistics is referred to as Univariate Descriptive Statistics.
