Linear Regression with R in Excel

Published 2025-07-29 by Kevin Feasel

Adam Gladstone continues a series on working with R in Excel via the ExcelRAddIn component:

In the first part of this series, I looked at using R in Excel to obtain descriptive statistics. In this second part of the series I am going to look at using R in Excel to perform linear regression, specifically using the lm() function. lm() is a real workhorse function. It can be used to carry out both single and multiple regression and different types of analysis of variance. For this demonstration I will only focus on single and multiple regression.

The workbook for this part of the series is: “Part II – R in Excel – Linear Regression.xlsx”. As before, the ‘References’ worksheet lists links to external references. The ‘Libraries’ worksheet loads additional (non-default) packages. In this demonstration, I use the datarium and broom packages. The ‘Datasets’ worksheet contains the data referenced in the worksheets.

Click through to see how you can perform ordinary least squares regression, multiple linear regression, and even logistic regression in Excel with a bit of R code. H/T R-Bloggers.

Building a Vector Data Demo Database for SQL Server 2025

Published 2025-07-29 by Kevin Feasel

Andy Yun has a new demo database:

Today, I have the honor and pleasure of debuting a new presentation for MSSQLTips: A Practical Introduction to Vector Search in SQL Server 2025 (you can watch the recording here too). To accompany that new presentation, I opted to create a new demo database instead of retrofitting one of my existing demo databases. And I’m sharing it with you so you don’t have to go through the headache of taking an existing database and creating vector embeddings.

Click through for Andy’s demo database, which is approximately 16 GB in size, so not a tiny one.

Gerhard Brueckl has an update:

7 months after the first official release of Fabric Studio, I am very happy to share the I just released the next major version with a lot of new features that make working with Microsoft Fabric from VSCode better and more intuitive than ever! The release includes some new capabilities that I wanted to get into the tool since the very beginning but back then the APIs just weren’t there yet. Finally they are and I integrated them into Fabric Studio v2.0!

Updates to sp_CheckBackup

Published 2025-07-29 by Kevin Feasel

Jeff Iannucci announces some updates to a free tool:

Since we introduced sp_CheckBackup last year we’ve gotten some great feedback on ways to improve this tool that helps you quickly and easily review the backup history for your SQL Server databases. We’ve even noticed a few things ourselves that we wanted to change as we used it more internally here at Straight Path Solutions.

Today we’re announcing a new version that includes some additions, corrections, and a few other adjustments that should be helpful. Here’s what new!

Read on for that changelog.
