Bug #: 47403
Summary: Let COVAR calculate sample covariance and add COVARP
Classification: Unclassified
Product: LibreOffice
Version: LibO 3.4.2 release
Platform: x86-64 (AMD64)
URL: http://en.wikipedia.org/wiki/Sample_mean_and_sample_co
variance#Sample_mean_and_covariance
OS/Version: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Spreadsheet
AssignedTo: [email protected]
ReportedBy: [email protected]
The current implementation of COVAR fulfills the following identity:
COVAR (R, R) = VARP (R)
This is obviously inconsistent. Also, there is no version of COVAR to be equal
to VAR in the same way.
Suggestion:
1. Redefine COVAR so that COVAR (R, R) = VAR (R).
2. Provide COVARP so that COVARP (R, R) = VARP (R).
