I would like to thank the creator of the video and all of the people who had a courage to raise a discussion in the comments! That was very helpful!
Really appreciate this video. Thank you very much!!
Very helpful and we would like more such explanations. Thank you Sir
Very helpful, thank you!!
Excellent!
This video saved me. Thank you.
Thanks a lot, great effort, and easily understandable.
Thanks you, we have a free course on SPSS, see researchhub.org/course/spss-for-beginners/
THANK YOU
Very helpful video n lucidly explained. Thank you Sir!!
Can you please suggest how to solve/proceed when we have heteroscedasticity problem in the data?
great
Is there anywhere I can cite this way of checking homoscedasticity?
I'd like to know what was the purpose saving the unstandardized predicted values. I didn't see them used in the second regression so, what should we do with them? Could anyone help me with this information? thank you
Why did you save the unstandardised predicted values (PRE_1), if we never used this variable?
Although we did not use the unstandardised predicted values (PRE_1) for Heteroscedasticity testing, from a regression point of view it shows the predicted value of the dependent variable for the particular observation. For example, for the 1st observation, while the actual sales value is 3454, based on our regression estimates the sales value for the observation is 2879. And the residual is just the difference between these two values, that is, 575 (3454-2879). I hope, now you see the use of the predicted values.
@@RESEARCHHUB Thanks a lot for the prompt and helpful reply 👍
@@Artyom109Zinchenko You may find this video interesting to learn more about the predicted value calculation. See ruclips.net/video/3MmMYZTLkSo/видео.html
Sir how we will interpret this in thesis, in terms of probability and chi test
Is there any way that I can cite this way of checking homoscedasticity?
Yes, SPSS Explained book by Charlotte Brownlow, Isabella McMurray, and Perry R Hinton
@@RESEARCHHUB I have checked the Hinton, McMurray, Brownlow (2014) book, but cannot seem to find this analogue. Would you kindly direct me as ti where I can find it please? Thanks
@@danielvellafondacaro792 I had the same question but I found an article which explained this dialogue. I put the citation below so you can have a look.
Astivia, O. L. O., & Zumbo, B. D. (2019). Heteroskedasticity in multiple regression analysis
great
