Best video I’ve seen explaining multiple regression analysis. I have watched so many but this is the best this far. Thank you

Glad it was helpful, Racquel! Best wishes!

I love the way you teach. You make things very easy. thanks for your kindness

You are so welcome, Kingley! Cheers!

Oh my gosh I needed this so much. I had to redo all my results and I'm trying to relearn how to use spss so I can run a multiple regression analysis. This was so helpful.

Woow..Thanks for a clear presentation sir..!

Hi there. Thanks for visiting! Best wishes.

How about there are more than one dependent variables? Shall I run Analyze>Regression>Linear for each dependent variables as much as number of DVs?

[@romentong9274]

Same question

[@aarushimahajan3050]

Hello Sir, What if the variables are measured on different point likert scale. For example 5 point and 6 point. How to run a multiple linear regression in such a case.?

[@muhammadbello4119]

How do you obtain the values of the independent variable.. I mean those numbers under interest and the other independent variable

[@couragee1]

thank you so much for this VERY helpful video.

Hi Nasir, thank you so much for your feedback! Thanks for visiting!

[@WScarfaceWars]

In my case: the standardized coefficients beta and the square of the part correlations give me 2 quite different rankings of the dependent variables

So as far as I understood you can just mark a categorical variable as a continuous one in order to include in the model. What's the point of logistic regression then?

[@mikecrowson2462]

Hello, thanks for visiting and for your question. First off, logistic regression is used when the dependent variable is binary and your goal is to predict the probability of a case falling into a target group (as opposed to a reference group) as a function of the predictors in your model. [there are actually other forms such as multinomial and ordinal, but I'm sticking to the most commonly used logistic regression model in this discussion]. OLS regression is used to predict a continuous dependent variable. With respect to your statement about 'marking a categorical variable as continuous for inclusion in the model', I would point out that the decision to do this does not convert your previously 'categorical' variable into a continuous one. SPSS allows you to change how you indicate the scaling of your variable under the Variable View tab, but whether you decide to have the indicator set to nominal, ordinal, or scale will not impact the mathematics behind the computation when running your regression. The program will give you the same OLS regression output when you perform your analysis with the variables listed in either way. I think of that option in SPSS as largely something that encourages folks to think about the scaling of their variables. Now, if you are asking about the decision by a researcher to treat an ordered categorical variable "as if" it was continuous (such as those cases where a researcher might treat a Likert type item, ranging from 1=strongly disagree to 7=strongly agree) in a model, then that is something different. Generally, the decision to do something like that is based on a variety of theoretical and pragmatic considerations, as well as the possible effects of doing this when it comes to meeting model assumptions. I'm not going to go into all the finer points here; but I will say that OLS regression technically makes no assumptions regarding the distributional characteristics of the predictors in the model. The only distributional assumptions pertain to the residuals (prediction errors). I hope this is helpful to you. Cheers! p.s., I do have a newer video on OLS regression here: kzbin.info/www/bejne/Zn-Xgmuwj86dmas

Hello 👋🏻 I’ve 1question to ask. As a beginner I currently run the spss. My hypothesis is to find “effect. From my knowledge regression test can do it. But, my data not normally distributed. Can i use regression to find my hypothesis with data not normally distributed?

[@swatioza26]

Hey Mike nicely explained Can we use regression for scale data for dependent and independent Variables are in scale... if Yes what will be the way to do so

[@mikecrowson2462]

Hi there. When you say 'scale ' data are you referring to the measurement setting in SPSS? That setting is sort of a catch-all for interval and ratio-level variables. You would use this setting if you are assuming your variable is continuous. Least squares regression assumes that your dependent variable is continuous. And generally your IV's are continuous. [It is possible to model categorical independent variables via the use of some type of dummy or effect coding system.] So running the analysis in SPSS with your variable set to 'scale' is the same as what I demonstrated in the video. Cheers!
