SAS Tutorial | Simple Linear Regression in SAS

In this SAS How To Tutorial, Andy Ravenna discusses how to perform simple linear regression in SAS. Linear regression is used across a wide range of fields to help predict a continuous target variable, something like “sales,” for example. Input variables are used to help predict the target variable. In simple linear regression, only one input variable is used to predict the target variable. Andy begins by exploring the formula for linear regression. Then he discussed ordinary least squares regression, which is how the parameter estimates are calculated. He’ll then demonstrate simple linear regression two ways: using SAS Studio and in SAS Visual Statistics, using SAS Viya.

Hi!
Thanks for checking out my video on simple linear regression in SAS. Let me know what you thought and if you found it helpful. Also, let me know if you have any questions. Have an awesome day!
Andy

best SAS explanation for linear regression

[Rachelannerox]

This is the best SAS viya tutorial I've seen! please do more!!

[dazzlingspark]

Best part about your videos, you don’t bore while making these informative videos.

[YuriBrGo]

Excellent Explanation. Just what I was looking for. Thanks Andy!

[satishsutar]

Greate Explanations on how to do reg. in SAS also you explained the concept of reg. in vary simple mannar.
thanks.

[Nipun_Chauhan]

You are an incredible instructor, thanks.

[mohho]

excellent sharing...I like it alot...Gonna explore more videos after this!!!!

[djrisks]

Excellent presentation Andy! I wish I learned about SLR like this, you break it down so well! Thanks!

[alakhns]

You are great in making thingd understandable. You spkoe very clearly and at the perfect pace.

[dolapoadepoju]

I don't have access to SAS yet but this is really helpful. Thank you for putting this out!

I like the idea (I did not watch the entire video because I feel I already know linear regression) and I especially like that it was posted over at SAS Communities (but I'm not allowed to comment on the post there, so I comment here). SAS Communities needs more basic statistics and basic programming tutorials; there are plenty of tutorials that appear at SAS Communities on advanced topics like Hierarchical Models and Quadratic Discriminant Analysis and so on; this is the first I have seen at SAS Communities on basic statistics. Furthermore, there needs to be some mechanism to search for tutorials at SAS Communities (if there is such a mechanism, I am not aware of it) and there also needs to be some mechanism to search for VIDEO Tutorials at SAS Communities. And maybe even post a comprehensive list of all such video tutorials at SAS Communities (and keep re-posting the list every week, because there are always new people joining, or searching for something).

This video exceeded expectations! thanks a ton!!

[SKAmabs]

thank you M. Andy I appreciate your videos

[navk]

Thank You for a great explanation sir...

I think there is a mis-statement at about 13:20 of the video:
"P-value very small tells me that this model is doing a very good job at explaining a lot of the variability of the target."

But that's not what the p-value tells you. It tells you that the fitted line is statistically significant, or in layman's terms that the fitted line did not happen by random chance. The r-squared tells you when the model is fitting a lot of the variability. You could have a p-value of 0.001 and a low r-squared, indicating that the fitted line is statistically significant but it does not explain a lot of the variability of the target. These concepts should be intertwined as the speaker said.

[heahkl]

andy, in your last model, the r square is 0.0914, how do you explain that small R square?

They gotta stop making you guys wear those Walmart blue polos 😂💀

"Simple"....Typical with SAS. NOTHING is simple. Everything is super complicated. More info than you need and all sorts of exceptions and that you just have to "know".
