Multiple regression is on the way. I am working on an extensive series of videos on Excel and JASP, including several variations on regression. Hope to add some logistic regression, Cox regression (survival analysis), and hierarchical regression, too.
This has been absolutely helpful. Thank you! I now really understand stuff I thought already understood before, but clearly needed a better refresher on.
I have had several requests on logistic regression. Plan to have something either later this semester.There is an excellent course on Course called "Logistic Regression in R for Public Health" that I recommend.
I love your pedagogical JASP videos and I ask all my students to subscribe to your channel. Will you soon be doing a JASP video on multiple regression?
Please tell all the other professors in your uni to do p values on linear regression...we do linear regression ALL the time in bio, physics, chem, and its easy to throw up a graph in excel and get the equation etc etc and find the relationships etc etc but it wasn't until I undertook my own personal research project and started wanting to find a way to run stats on a line that looks like there is no significant change on the dependent variable over a range of concentrations of a toxin, that I finally wondered if there was a way to determine this rather than running anova at each concentration of a dose response line and I am still probably doing it wrong, but I learned something.
These videos are amazing! I am being asked to find the linear correlation coefficient between the two variables. What number do I look for in JASP. to report that number? I assume I use the Regression Linear Regression, right? Is the the H1 unstandardized?
If you are examining only two variables, then the r correlation coefficient will be exactly the same as the b regression coefficient. If you have multiple predictors in your regression model, then b will be unique to each predictor. The standardized regression coefficient is r, the unstandardized is in terms of the variable being measured. Hope that helps
Great vídeo! I have a question (from a non statistician): What can we do if the Durbin-Watson statistic does not fall between 1 and 3, what are my options as researcher? Should I drop my attempt to do a regression? Thanks a lot
Good question...the Type 2 error would only relate to the ANOVA testing whether the entire model (or additions to the model) are significant. You could also examine the confidence intervals. Assuming that you have a large sample size, which is kind of necessary to run a regression in the first place, power should not be an issue. That said, I don't know of a specific test. Best!
Yes, eventually...I am teaching a class this fall that will cover various forms of regression and I will be adding new videos for each one of them. It is not going to be right away, however.

Your video is a gift from heaven!!!!! THANK YOU!
These videos are amazing! If you ever have time to do a multiple linear regression in JASP, I will forever be in your debt!!

So grateful for these videos, helps a lot to my undergrad and graduates students.
This has been absolutely helpful. Thank you! I now really understand stuff I thought already understood before, but clearly needed a better refresher on.
Glad it was helpful! thanks for the comment
This is a fantastic video. It helped me out a lot with my statistics project, thank you!
Please make a JASP video on logistic regression🤪🙏🏻😜
You are such a pedagogical statistics teacher and I cant find any good video om logistic regression using JASP. Please.
Very helpful and well explained. Thank you so much.
I hope you will SOON do a JASP video on logistic regression🙏🏻🙏🏻🙏🏻

Watching as a UoPeople Student .
i love how you made this
You guys are Godsent.
Thanks for your video. It's very good!
Thank youuu!!! Very clear voice and explanation
Glad it was helpful!
Thank you so much! This helped a lot
Very nice, good job
life saver

Amazing explanation
Thank youuuuu
Can u plz do a multiple régression using the JASP. Thank u
why did you choose the durbin-watson value of H1 and not H0?
hi, would you mind to give an explanation on how to use Weighted Least Squares in Linear Regression on JASP?
Good question and I don't have an answer off the top of my head. I will look into it. Great suggestion.

How do you know which numbers the min and max should not exceed?
isn't the formula, Y = a + b * X ?
Great vídeo! I have a question (from a non statistician): What can we do if the Durbin-Watson statistic does not fall between 1 and 3, what are my options as researcher? Should I drop my attempt to do a regression? Thanks a lot
Is there a way to find beta, or the probability of a Type 2 error with this test? What can I do to find it? Awesome explanation, by the way!
Good question...the Type 2 error would only relate to the ANOVA testing whether the entire model (or additions to the model) are significant. You could also examine the confidence intervals. Assuming that you have a large sample size, which is kind of necessary to run a regression in the first place, power should not be an issue. That said, I don't know of a specific test. Best!
for the equation, did you minus bx because your b was a negative answer? my b is positive so does that mean I should add bx?
Correct...the formula is bx+a, but in my case the b was negative, making it subtraction. Your b is positive, so it will be addition.
@@ResearchByDesign thank you!!
Do you plan to do some JASP videos on logistic regression?
Yes, eventually...I am teaching a class this fall that will cover various forms of regression and I will be adding new videos for each one of them. It is not going to be right away, however.
Thank you for the amazing videos.
When you will share simple logistic and multivariable regression?
Thank you
