-*<math>Array</math> is array of integers or reference to the cells containing array,
-*<math>GroupBy</math> is a method that performs the analysis by Columns or Rows,
-*<math>NewTableFlag</math> is a flag that determines how the output should be displayed.
-COVARIANCEDATAANALYSIS() calculates the average of product of deviations of values from the means of each data set.
-== Description ==
-COVARIANCEDATAANALYSIS(Array, GroupBy, NewTableFlag)
-*Covariance is a method used to determine the relationship between two data sets.
-*<math>Array</math> can be numbers or can be names, arrays or references containing numbers.
-*Values containing text, logical values or empty cells are ignored.
-*Argument <math>GroupBy</math> can be "Rows" or "Columns".
-*<math>NewTableFlag</math> can be a logical value TRUE or FALSE. If omitted, Calci assumes it to be TRUE.
-*If <math>NewTableFlag</math> is TRUE, output is displayed on a new ZSpace cube. If <math>NewTableFlag</math> is FALSE, output is displayed on the same spreadsheet where command is written.
-*If data is invalid, Calci displays NaN error message.
