Description Harald Weedon-Fekjær 2017-11-27 12:29:55 UTC
Description:
Nice to see linear regression in the open source Libreoffice menu. Linear regression in an office package is obviously a winner for teaching, but one key part is missing; Confidence intervals for the regression coefficients :-( In almost any data analysis quantification of the uncertainty is key, telling us if the findings might be only random noise. Microsoft has a confidence interval option in their Excel analysis toolpack - Is it possible to also add it in Libreoffice?

Best regards,
Harald Weedon-Fekjær, Researcher/biostatistician PhD

Actual Results:  
Regression coefficients without any confidence intervals

Set as NEW as it is a valid feature request.

The commit http://cgit.freedesktop.org/libreoffice/core/commit/id=b7a02f2bb66b990289eb7f4dc80069d1545179a4 in master adds support for multivariate regression. This also adds confidence intervals for each estimate (slopes and intercept). The confidence level is configurable (default is 95%). All these features are available in the latest dev builds and will appear in 6.2 release.
