- In this video I show you how to use categorical independent variables, i.e. ordinal or nominal variables in your regression analysis.

Good shit, homie. I was like, how the fuuuuuc do I do this logistic regression when most of my categorical variables have many values... I couldn't wrap my head around it because the regression values didn't make any sense. I'm glad I found this video!
Great!!! And thanks for the feedback : )
Frrr g good shit , this shit is lit fr yo one thousand
im into learning german and ML in same time and found your channel. how lucky am i?
Very informative. My textbook wasn't helping much. I liked the simplicity.
Thanks a lot for your feedback!
Amazing Explanation. Please keep it up❤❤
Thanks for the excellent content. How should we report the data for a scenario where we have a categorical variable with three or more categories (2 or more dummies), where SPSS will generate a row with different Beta and significance for each dummie? I have seen articles where this scenario happens and only one row (Beta/significance) is reported to represent the whole variable. Thank you.
V. Good your way of teaching is superb
Thanks a lot! Regads Hannah
what to do if we have a categorical varilable has more than 3 values, for example 10, do we need to create 9 more columns? What to do with ordinal variables? Thanks a lot
My concern why ranch has one scoring number why we can’t give 1-3 or 1-5 number for example we are conducting survey
Helpful!
Thanks! datatab.net/
Great video
Thanks!!!
Can you please metric and nominal I assume nominal which meant selected options numbers, but how metric does works
I have some question: I have an independent categorical variable with 3 categories (3 dummies). Then I generate my model and I found that just 1 of my 3 dummies is significant. Should I generate a new model removing those dummies that aren't significant? or should I report every Beta despite they aren't significant?
Hi, if you have 3 categories you have 2 dummies 3-1=2 . On the fly, I would say report everything! But that may be different from case to case. Regards, Hannah
@@datatab haha ok, I want to use the multinomial regression as a descriptive way to describe de relation of my independient variables with my dependent variables. And that why if I use n-1 dummies I'm not able to describe that missing category :'( .
By the way, if I use n-1 dummies I get less accuracy in the predictions than if I use 3 dummies, also change the accuracy of predictions depending in the set of n-1 dummies that I use for my model 🥺
Hello, I have a question. Is it possible to do regression analysis for two categorical variables and one continuous variable as independent variables, and a continuous variable as dependent variable?
Hi, yes that should be possible!
Thank you
Amazing thank you
Many thanks for your nice Feedback! Regards, Hannah
What does the y intercept indicate?
I have question, on my research paper i have one independet continous variable and four dependent variable in which three dependent variables are categorical with more than two caracterstics or values and one continous variables with more than 2 values. Therefore, what types of regression analysis should i use
Terrible pronunciation :(
Please especially check how the term 'variable' is pronounced.
Thanks for your feedback! We are constantly improving : )
