Understanding the Summary Output for a Logistic Regression in R

[@qubits2819]

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

[@kyranadams1616]

literally the most anxiety inducing audio

[@conjurecorpse8209]

LOL

[@Lapelu9]

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!

[@jaf6969]

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

[@mariyapak428]

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!

[@nathanthompson8652]

This is a brilliant explanation

[@akoredeadebayo4269]

The model diagnostics was very helpful

[@surendarsuren7460]

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.

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.

[@benphua]

How about being glad that a busy expert took the time out of his day to record something useful for others for free, thanks for providing this tutorial Jeff.

[@saurabhchoudhary4572]

@@benphua that's true but we want to hear the expert and not the noise this is something that can easily be taken care of, apologies in advance if this sounds rude.

[@inf3rno691]

@@benphua if you want to upload a video on youtube, do it by the right way. Ether dont do it at all. Its an 7 minute video. You can keep your room silent these 7 minutes.

[@abhisheksaurabh4584]

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

[@KhaLed-pb4pu]

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!

[@zjwunwun9075]

not sure what the data is nut, but the function to get this output Called is basically just model1 = glm(marriagevariabe ~ churchvariable + sexvariable + educationvariable, family=binomial, data=dataused) and then summary(model1)

[@ekvinaysayaraj6071]

3:42 goodness of model

[@analyticsc7548]

Thanks, finally the finer details explained.

[@b.harish9751]

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

[@illan731]

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?

[@aninditabrahma9637]

Thanks a lot Jeff...!! :)

[@xiaoluzheng9303]

thanks, super helpful for R novice

[@christianott7937]

thank you very much for this short recapitulation

[@anushkabanerjee2510]

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

[@georglangthaler4637]

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 ^^

[@epsilonzeromusic]

Georg Langthaler The probability to be happy.

[@mauralievano5037]

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

[@HuyenNguyenNgoc-v3e]

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

[@jhablinski]

Hi Jeff, great little tute. Thanks a lot. Is there any R function which can run multiple glm fits using all combinations of independent variables in a data set to find the optimal logistic model for a given response variable. I.e. a function which indicates the model that Minimises Residual Deviance?

[@nitishgupta8]

+Josh Harlen i am looking for a similar answer , were you able to find the same ?

[@marcosj685]

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

[@tomaszwodarczyk6357]

I would be good to explain the dataset up front. Good work anyway.

[@baburao8511]

How to find f value from the glm model

[@prakashkrishnan7132]

How the null deviance calculated as 79.763 & Residual Deviance calculated as 49.268

[@aparnanayakn]

Thanks for the information.

[@flachboard84]

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

[@98kof98um2]

is it possible to include a CLASS statement like sas in R logistics Regression? Thx. Nice vid by the way.

[@melissalabelle9357]

how would i make a graph for something like this tho

[@Engversity]

I hate this phone vibration

[@lmeech1]

Very helpful, thank you!

[@MiladShaddelan]

Thanks a lot

Great, Sir. I want anova(glm)

[@MarkBetterDev]

if you got limited time play at x1.25...plug

How do you interpret the coefficients of splines used via the ns() function? stackoverflow.com/questions/65620624/interpretation-of-cubic-spline-coefficients-in-r

[@inf3rno691]

All these sounds of your phone, microphone, etc.. destroyed these usefull informations you tried to transmit

[@karthik6505]

Very irritating background which loses the good work you are trying to do!

[@cezbabe]

Too fast! Can you explain it slower and more thoroughly in layman terms in another video, please?
