Linear Regression - made easy

Simple linear regression models don't need to be scary. This video will take you through the basics of how to interpret linear regression results. If you are learning regression modelling or just learning statistics and quantitative analysis then this is a good place to start. Data science and research often address questions by looking at how much of a change in one variable can be explained by a change in another. Linear models are used to answer this question. They can also be used to predict the value of one variable given the value of another.

Awesome job as always. Thank you for all you contribute to stats knowledge.

So glad to have found you as I am sure many others are. I wish I had found you before I trudged through the dull micro-lectures provided for my online University masters degree. You make the subject relative and understandable. I am going to watch everything. I need to. Thank you!

Thanks for the video, Greg. Please could you do a video on the assumptions of linear regression as a sequel to this video. Thanks

Hi, for multiple linear regression, can a percentage change (a reduction) in the level of say blood glucose, be the continuous dependent variable?

first comment to say thanks from the heart

Remarkable lecture, thank you so much.
Q. Please share me/us a video lecture of multiple regression plot with confidence interval and annotation of the equation and significant level?

[psnacademy]

If the y-intercept is meaningless, then the line can be anywhere along the y-axis. If so, then how it will predict y for an unseen x?

Did anyone finde that cheat sheet Greg mentions at the end of the video?

[buffaloperformanceandanaly]

Hi Greg! Thanks for the great videos. I am trying to figure out how to filter out outliers and then run a linear model, but am getting stuck. Any suggestions?

[carlosferrer]

Hi Greg. Your videos are awesome. Do you have one explaining how to perform multiple logistic regression in R?

[MathwithLukgaf]

Thanks for all you do, Greg. Please I have a quick question. Please which result should I rely on (the lm or t-test) if I get the effect of the independent variable with lm but the value of p value is not less than 0.05 when I compare them with the t-test using the same data. Thanks
