Simple and Multiple Linear Regression

Linear Regression in Statistics: The linear regression distinguishes between simple and multiple linear regression analysis.
SIMPLE LINEAR REGRESSION
In the first case, simple linear regression, the aim is to investigate the influence of an independent variable on a dependent variable.
MULTIPLE LINEAR REGRESSION
In the second case, multiple linear regression, the influence of several independent variables on a dependent variable is analyzed.
In both cases, it is a prerequisite that the scale of measurement of the dependent variable is metric.

Best stats explanation around!

[@areejbader96]

wow easy clear and informative , Thank you so much !

[@mithonachann5243]

Great explanation and easy to understanding!!!

[@cococnk388]

Thanks for this great video... which type of plot can we use tu display multiple regression?
in order to have a visual idea about the statistic ?
Thanks

[@dr.battulapradeep1183]

Very very useful and easily excutable tool.Thank you.

[@datatab]

Glad you like it

[@medleminabdouli1453]

Thank you soo much!!! It was definitely helpful.
If it is possible would you please make for me and my classmates a video tutorial about relative weight analysis or relative importance analysis, in which are struggling to understand properly.

Best explication, thank you so much :)

Thanks : )

Hello! Thank you for your videos, they are very helpful. I would like to ask you sth. If I want to compare the salary between two groups of professors (public and private sectors) and years of experience, which statistical test do you recommend me to use? Thank you!

[@datatab]

Hallo, thanks for your nice Feedback! In this case i would calculate a Regression! Regards Mathias

[@cococnk388]

You can first plot a relative frequency histogram... to see the distribution of the salary for each group..
A scatter plot for both groups (public and private)
Since for both group we do have one (not two) independant variable which is years ...
If there is a linear relationship we can go on with regression (prediction)
or you can claculate the "coefficient of determination" which is r * r %
we calculate the least squares equation ...of both scatter plots
Then interpret b..
if coefficient b of group B is > than coefficient b of group A it means for an increase of one unit on the x axis the salary varies more ....as compared to group B
If someone thinks other wise kindly help me know in the comment section.
Thanks

[@vsssarma]

Can you teach multi-variable, non-linear regression? Or suggest a source? Thanks.

[@alialshebami8408]

what exactly is the difference between influence and prediction? you explained it in the first minute of the video.

[@aishwaryar1998]

In multiple linear regression can independent be categorical variable and how can I check whether a data is linear of non linear especially if I have categorical variable?

[@datatab]

Hi please have a look here: th-cam.com/video/bnjPzHQ04Ac/w-d-xo.html

[@dr.battulapradeep1183]

what is mean by coefficients here. Please, interpretation required in layman language

Hey,Could you explain from where does this .14 &1.2 comes?

[@datatab]

Hello, where in the video is this? I do not know the video by heart either : ) Otherwise I would have to watch everything first : )

[@thymenhinssen2325]

@@datatab At 5.35. But I think you are just using it as an example right? It could have been any number?

[@dev9545]

Best explanation 👍

[@datatab]

Thank you 🙂

[@strangeosyndro272]

I love how Europeans teach. American videos are filled with non necessary things. Germans eyc are like, "This is what it is, this is how you calculate it, this is why you need to".. simple and straight forward. Love it

From where did the coefficients from the equation come from?
Thank in advance

[@joppe191]

I also have this question

[@kelvinchong1736]

Pearson coefficient

[@mehdi.sajadi]

what should be substituted for male ? 😟 It's not a numerical value !

[@datatab]

Just 1 for male and 0 for female or the other way around!
