Understanding the Summary Output for a Logistic Regression in R

[qubits]

Videos like these make youtube statistically significant in our life! this is Gold...

[kyranadams]

literally the most anxiety inducing audio

[jaf]

This type of video is Gold dust...thanks!

Have been stock for a couple of hrs trying to figure how to explain statistical significance of my data and you solved everything in less than 7 minutes. Thanks!

Excellent job explaining the base categories. I have watched a lot of tutorials and this one by far does the best job explaining what is a 'higher'/baseline category. I think many people get confused with that and there is actually not much about it out there that is being explained. I wish I saw more videos about how do we know what category (for dependent or indecent variable) R is showing us in those tables. Thanks again for filling that gap!

next time when you record a video please make sure all other external objects are put to silent. so much of external noise. Phone kept vibrating, and whole lot of other sounds.

I have a question please, because it is (-2.9075 x church), so church variable needs to be minus so that we get plus the result
which means the less we go to church, the more happy our marriage is, is that true

Is there a video for the raw data and the steps you followed to do the actual analysis that generates this output? would be great if we can see both videos!thanks!

[surendarsuren]

Thanks Jeff..it was useful for me..
Pls add some more details like backward selection with more categorical parameter, Best Fit model, anova test, validation etc.

Thanks! What about lrm coefficient outputs? There is no intercept and if your formula is 6 dependent variables ~ 2 independent, there are 6 + 2 coefficients?

[anushkabanerjee]

What would be the interpretation if I found the difference between the deviances is zero??

[georglangthaler]

Hello

There is one question.
How (more detailed) do you interpret the given coefficients talking about odds/log odds and probability.

E.g., an increase of 1 unit education (let's say this is a year) has XX effect on being happy in mariage. Is it 1 unit education increases happyness by XX percent? Oder the probability to be happy?

I hope you get my question there, I am already confused ^^

Hi Jeff.
Thanks for the excellent explanation of the summary output. Could you please explain the meaning the 'Number of Fisher Scoring iterations: 5'? In addition to a technical explanation, an intuitive explanation would really be helpful.
Regards, Abhishek

[akoredeadebayo]

The model diagnostics was very helpful

[b.harish]

Thanks for the video, can u explain what is the significance of Fisher Iterations in the output?

[marcosj]

I'm trying to make an estimated logistic equation out of this though. with y, x, b0, b1 etc.

[mauralievano]

I think at the end of the video you say that it reduces statistically significance and find it a bit confusing, I think it actually increases the significance because it reduces the probability of finding this data by chance, and so increases statistical significance relative to the simple model

[flachboard]

Do you have a definition of the deviance residuals in greater detail?
