Do you have any tips on excel to: - select the right variables - check if the required assumptions are match - checking outliers and missing values - how to test several combinations of variables
i am doing a question comparing 2 models which each have 3 independent variables. Can i use the fact that Model 2 has a lower standard error of the estimate than Model 1 as a predictor of the dependent variable?.. since this would mean narrow the width of the confidence interval and therefore give smaller margin of error in my prediction of the dependent variable? Thanks
Thank you. I was doing analysis and i got beta value positive 0.026 but the sig.value is 0.6. So should i reject the hypothesis ? Does it mean x and y are negatively related ?
Probably the best clear yet more in depth explanation on the interpretation. So good! Do you normalize data before the regression? Does it matter? Thanks
To estimate the Marginal Value Product (MVP) and Marginal factor cost (MFC) equated to allocative efficiency ratio or from regression coefficient of the variables
Is there a way to determine if one of the independent variables moderates the relationship of the other independent variable and the outcome using multiple linear regression?
sir please help me my problem is - Another persons explain his model - RSEI = 0.098*NDVI + 1.019*WET - 0.025*NDSI - 0.001*LST + 0.007 (R2 =0.998) 1. The WET must increase by 0.098 if the RSEI increase by 0.1. Nevertheless, the increased WET and the decreased LST occurred at the same time . 2. Therefore, RSEI increase will be more than 0.1. If the LST decrease by 0.098 and the WET increased by 0.098 the RSEI will increase by 0.10001. How its explain? My model is - RSEI = 0.9396*NDVI - 0.0074*WET - 0.22496*NDSI + 0.04665*LST + 0.0664 (R2 =1) So,1. If the RSEI increase by 0.1 then NDVI must increase ................? 2. RSEI will increase by 0.10001, Then LST decrease by .................? and NDVI increased by ..................................? How this model explain above mention two point? Please answer me. and help me.
Please watch my short video, Regression - In Brief 2of3, for interpretation of regression result. In your study, RSEI rises(falls) by 0.098 unit for every 1 unit increase(decrease) in NDVI, with the other variables held constant.
Sir RSEI is the dependent veritable and other WET, LST, NDSI, and NDVI is the independent veritable. I am calculated multi regression. but i can not explain the model. sir I want to explain my model.
Thanks Dr. Pat Obi , unbelievably clear explanation , don't know why others over complicate these concepts!
Yeah am grateful for your presentation, will fail no exam on this topic, thanks once more Sir, you are indeed a genius
Seriously, these explanations are so clear and simply brilliant! Thank you so much!
Watching this lecture is much better than attending my actual lectures online. Thank you!
Thanks for your kind comment :-)
Honestly i have been helped...thank you for providing such great clarity on the topic.#preps for my next month exams
You, Sir, are a lifesaver. Thank you so much!
You are a wonderful and intelligent human being. Thank you
Thank you for breaking this down. I feel like partial cost of my PhD program should be paid to UA-cam (that's bad I know).
You're very welcome!
@@PatObi me too. UA-cam has helped me a lot during my PhD journey
Oh My - so nice to see this video- you were in the strathmore uni orientation day...i am happy to see you here professor
This presentation is phenominal. May God bless you, sir.
Thank you. And you too.
Thank you so much really.....so simple explanation..that no body can give..

Thank you.
I was doing analysis and i got beta value positive 0.026 but the sig.value is 0.6. So should i reject the hypothesis ? Does it mean x and y are negatively related ?
what do i do if my r square is less 10% but the model is significant?
thank you so much for the thorough explanation!
If i have a model where the p value as a whole is not significant, but one independent variable is significant, can it still be reported?
Sir if R square in regression model will around . 2 or. 3 is it problematic?
Hello Sir, where did you get the number x1=52 and x2=17? maybe i have missed it on your presentation. thank you
Very helpful presentation. Thankyou sir!
Wow. Thanks a lot. Now I can interpret my data very well
You're welcome!
How can we calculate the error term
Thanks Pat!
Probably the best clear yet more in depth explanation on the interpretation. So good!
Do you normalize data before the regression? Does it matter? Thanks
Thanks for your kind comments. No, I don't think it's necessary or even appropriate to normalize regression data. Just my opinion :)
No need to normalize unless you wish to. Sorry for late response :-)

Good work 🤝
Thank you so much for this
Thanx a lot , i can now her heart❤️
Thnx. Very helpful video
thanks lo for every words...
Thank you so much
Thank you so much, Sir! Your videos are very helpful!
You're welcome!
Top guy Pat
Thank you Sir.
Verry helpful
Is there a way to determine if one of the independent variables moderates the relationship of the other independent variable and the outcome using multiple linear regression?
I'm not sure, Lorenzo, except perhaps in the context of colinearity and in a different case, inclusion of interaction terms. Please ask others.
I owe you!
Hello! How to calculate p test manually? is there is formula in multiple regression?
You can watch the 2nd half of this video: ua-cam.com/video/k07RULqaFOk/v-deo.html
my god will bless u
Thank you.
sir please help me
my problem is -
Another persons explain his model -
RSEI = 0.098*NDVI + 1.019*WET - 0.025*NDSI - 0.001*LST + 0.007 (R2 =0.998)
1. The WET must increase by 0.098 if the RSEI increase by 0.1. Nevertheless, the increased WET and the decreased LST occurred at the same time .
2. Therefore, RSEI increase will be more than 0.1. If the LST decrease by 0.098 and the WET increased by 0.098 the RSEI will increase by 0.10001.
How its explain?
My model is -
RSEI = 0.9396*NDVI - 0.0074*WET - 0.22496*NDSI + 0.04665*LST + 0.0664 (R2 =1)
So,1. If the RSEI increase by 0.1 then NDVI must increase ................?
2. RSEI will increase by 0.10001, Then LST decrease by .................? and NDVI increased by ..................................?
How this model explain above mention two point?
Please answer me. and help me.
Please watch my short video, Regression - In Brief 2of3, for interpretation of regression result. In your study, RSEI rises(falls) by 0.098 unit for every 1 unit increase(decrease) in NDVI, with the other variables held constant.
Sir please send your 2 of 3 video link. because I want to interpreted my model. thank you sir.
Sir RSEI is the dependent veritable and other WET, LST, NDSI, and NDVI is the independent veritable. I am calculated multi regression. but i can not explain the model. sir I want to explain my model.
Can you send me this ppt or docx
