| Did you check the Language Reference? There's a Standard Deviation formula but covariance you'll have to calculate yourself. |

in general a product not overly complicated comes with three manuals
- installation and customization ( the name tells )
- user guide ( general considerations and advices on the use )
- user reference ( detailed explanation of the - for example - commands, keyword, syntax )
and the word manual is usually implied when referring to them
and since cobol is a programming language the shortcut is "language reference" |

At the top of the page is a link to "IBM Manuals". You should see the Language Reference manual for your version of COBOL - just click on it. |
