Description: It marks an error in the regression analysis of four variables, specifically when one of the values of the variable is equal to 2, any other value in this data does not cause an error. I mark it with an asterisk. Data: Y X2 X3 X4 4 *2 4 1 7 4 7 2 8 6 5 3 5 8 8 4 9 10 4 5 6 12 8 6 5 14 5 7 Steps to Reproduce: 1. Open Calc 2. Enter the data that I have shared with you in the comment, except do not include the asterisk. 3. go to Data/Statistics/Regression with the following options: Select all independent variables (X) and their names. select the dependent variable (E) and its name. check the checkbox indicating that variables have labels. select the cell where the results will be returned select the check box grouped by columns select the Linear Regression check box the confidence level of 0.95 do not check the Calculate Residuals box.

Thank you Luis! I can see the same in: Version: 7.4.4.2 / LibreOffice Community Build ID: 85569322deea74ec9134968a29af2df5663baa21 CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3 Locale: en-AU (en_AU.UTF-8); UI: en-US Calc: threaded and: Version: 7.6.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: e125e6623fa1c0f39d927bb37547ca6d1e299cb1 CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3 Locale: en-AU (en_AU.UTF-8); UI: en-US Calc: threaded Same thing in: OpenOffice.org 3.3.0 OOO330m20 (Build:9567) Trying to find some logic in it, I think it has to do with having two series with a skewness of 0. Changing any number in X2 or X4 will change the skewness and give results in the LINEST array. MS Excel does *not* have the same issue. Microsoft® Excel® for Microsoft 365 MSO (Version 2212 Build 16.0.15928.20196) 64-bit
UI Regression dialog ask for independent X variables. As X2 = 2 * X4, your variables are not independent. X3 has no effect on the bug.
Dear Luis Salcido, To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year. There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present. If you have time, please do the following: Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/ If the bug is present, please leave a comment that includes the information from Help - About LibreOffice. If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice. Please DO NOT Update the version field Reply via email (please reply directly on the bug tracker) Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not appropriate in this case) If you want to do more to help you can test to see if your issue is a REGRESSION. To do so: 1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/ 2. Test your bug 3. Leave a comment with your results. 4a. If the bug was present with 3.3 - set version to 'inherited from OOo'; 4b. If the bug was not present in 3.3 - add 'regression' to keyword Feel free to come ask questions or to say hello in our QA chat: https://web.libera.chat/?settings=#libreoffice-qa Thank you for helping us make LibreOffice even better for everyone! Warm Regards, QA Team MassPing-UntouchedBug

The problem is still not resolved, I have tried it again in LibreOffice version 24.8.5.2 (X86_64).
Let's reformulate: LINEST function, in case of dependent variables, should carry out calculations without these dependent variables, like MS-Excel is able to do. For instance, in attachment 184913 [details], =LINEST( A2:A8 ; B2:D8 ; 1 ; 1 ) should return the same result as =LINEST( A2:A8 ; C2:D8 ; 1 ; 1 ) because X2 data in column B are dependent of X4 data in column D
