Many thanks for your lession. I have a question if you please can reply me. How can the same analysis be made with n knot points and several linear segments? Thanks
Why did you pick the value of 90? Is there a statistical way of determining the cut of values for a scatterpolt that could have a number of cutoff values? Thanks!
thank you. I have a question, is it possible to compute the b2 value without the minitab lm function that seems to compute it , is it possible for example to do this in excel ? Brgds
Yes, you can do the same thing in excel. To do so, you have to add the "data analysis" add-in in excel and use the regression function in that tab. you can google and will find plenty of instructions on how to run regression in Excel.
@@sxmirzaei Thank you very much , I have found it in the meantime and it works very nice, thanks to you for your video that triggers my interest ... And more thanks for your fast answer and follow up ...Brgds
thank you , this helped me a lot, I'm trying to apply the same model but with multiple knots, your way is clear and straightforward, thank you
this helped me a ton with homework thanks a bunch!
Very interesting methodology! Thanks! It has helped me a lot. How would you implement this same methodology for three slopes??

Excellent video! If I were to add a second break to the equation, would the dummy knot then be 0, 1, and 2? Thank you!
Amazingly explained , helped a lot
Great video! I was wondering how to plot the linear regression in R using ggplot so I can visualise the break point. Many thanks!
Great Thanks. I hope if you could make videos for other types of regression.
Thanks! I did have to put you on 0.75 speed for some of it but overall this was really helpful.
You are a lifesaver
I'm literally sitting in her class right now trying to figure out how to do this.
So in the right of the breaking point, the [new b ]was actually (b1+b2), right? But how can I get the 95% CI or p-value of the [new b]? Thanks!
Hello. How would you do this with multiple variables?
Thank you so much.
Why did you pick the value of 90? Is there a statistical way of determining the cut of values for a scatterpolt that could have a number of cutoff values? Thanks!
I picked the breaking point visually by looking at the graph.
Great video! Can I download the code and data somewhere?
Can we apply standard deviation al9ng with graph lines?

Great tutorial but you need to slow down you are going to fast in the audio I have to pause and listen again. Thank you.
adjust the speed using the gear icon in the video's bottom bar
