Description dajoker 2011-03-22 14:14:29 UTC
OpenSUSE 11.3 x86-64
LibreOffice 3.3.1

I've been enjoying using LibreOffice this last couple of weeks instead of OpenOffice but in class today the instructor took us through linear regression.  While I have found the LINEST tool it's not quite the same experience as some other productivity suites provide.  I'm using Gnumeric's linear regression option successfully and that's okay but I'd rather do this natively within OpenOffice.  Selling my classmates on LibreOffice hasn't been too hard since it's done almost everything they have been able to do without any issues (have been some problems with microsoft's proprietary XML format rendering in odd cases, but that's it so far) but most of them are not on Linux so using Gnumeric isn't an option.

I'm willing to test what anybody comes up with or even help with creating it but I must admit I'm no statistician.

Expected Results: Linear Regression tool that is simple to use and powerful.

Actual Results: LINEST function does some of this but not in an easy-to-use way, and without as many data points in the output.

Please be more specific about what you are missing and what you get in Gnumeric and not in Calc.
Comment 2 dajoker 2011-03-24 20:06:50 UTC
Output like the following by running a quick tool that just selects the independent and dependent variables' data, plus provides other options.  This is similar to what is provided with other proprietary packages and, as far as I know, is not part of OO.o or LO.  Sorry about the spacing:

You can get all the needed values using LINEST. I do not think, that LO should integrate such a wizard. Such wizard can be provided by an extension. Please have a look at http://openoffice.org/projects/sc/downloads/download/Data%20Analysis/Statistical%20data%20analysis%20tool.zip
[I don't know whether it is on the extensions-website, because it is down currently.]

Dear bug submitter!

Due to the fact, that there are a lot of NEEDINFO bugs with no answer within the last six months, we close all of these bugs.

To keep this message short, more infos are available @ https://wiki.documentfoundation.org/QA/NeedinfoClosure#Statement

Thanks for understanding and hopefully updating your bug, so that everything is prepared for developers to fix your problem.

Comment 9 dajoker 2012-08-14 17:03:01 UTC
To resolve the NEEDINFO state, there is still no advanced/nice linear regression tool in LO as far as i can tell.
Comment 10 Roman Kuznetsov 2018-07-29 17:41:40 UTC
There is Data->Statistics->Regression now in LO 6.1.

I don't know is it nice tool or not, but it there is.

Regina, what do you think? May be close this enhacement as WFM?
Comment 11 Regina Henschel 2018-07-29 18:53:23 UTC
Yes, it can be closed. In case the existing tool needs to be improved, a new bug report is necessary anyway.
