This is extremely well-explained, thank you. If the missing category overwhelmingly consisted of females in your example, would this mitigate this effect on X? And can the impact of including a missing category be identified by examining the estimates from the missing category and seeing if they are similar to any of the other non-missing categories?

great explaination. Here is the code explained in the lecture: nSimulations = 100000 nSample = 100 Y = numeric(nSimulations) for(i in 1:nSimulations){ X = runif(n); Y[i] = mean(X) } sigma = sd(Y) mu = mean(Y) hist((Y-mu)/sigma, breaks = 50) Here, I have scaled and shifted the random variable to make it the standard normal. Also, you can replace runif() with any other distribution of your choice.

Hi, the Hosmer-lemeshow works in logistic regression, but what about poisson regression( binary dependant variable in cross-sectional studies) what options for goodness-of-fit do we have?

You do not need to multiply logicals by 1 in R to make them integers.

Excellent explanation. Thanks!

Simple script, clear explanations!

You cleared many doubts, thank you!

Merci beau gosse

Great video, thank you. Simple, easy to follow and straight to the point!

Thank you sir.

good morning.sir. I have a question:what is y1 and y0 presentation?

I love you thanks for doing this!!!

This is pure gold. You sir are a diamond in the rough

hello, how do you move around the lines? I was keep pressing shift+enter to go below the line without producing something..

if i have a smaller p value than alpha score 0.05. what should i do if my model are not fit well?

how to do this test by eviews 8?

Hey, in the line > hl <- hoslem.test(mod$y, fitted(mode), g=10) it should not be "mydata$y" instead of "mod$y"??

Hello! Thank you for this video. But I have a question. The X-squared and p-value of Hosmer-Lemeshow test in R and SPSS is very different. Why?

hey i tried lot but following errors occure > hoslem.test(result,phat,g=10) Error in hoslem.test(result, phat, g = 10) : object 'phat' not found > hoslem.test(result,fit,g=10) Error in hoslem.test(result, fit, g = 10) : object 'result' not found > hoslem.test(diagnosis,fit,g=10) Error in rank(x, ties.method = "min", na.last = "keep") : unimplemented type 'list' in 'greater' > hoslem.test(diagnosis,fit,g=8) Error in rank(x, ties.method = "min", na.last = "keep") : unimplemented type 'list' in 'greater' > hoslem.test(data,fit,g=8) Error in rank(x, ties.method = "min", na.last = "keep") : unimplemented type 'list' in 'greater'

Beautifully explained! Though i listened to it like 20 times. Thank you very much!

thank you for this video ... this has been really helpful

when 'm trying find Hosmer-Lemeshow tests this appear am using mutivariate logistic Error in model.frame.default(formula = cbind(y0 = 1 - y, y1 = y) ~ cutyhat) : variable lengths differ (found for 'cutyhat') can u help me if possible thanks in advance

Super useful. Thanks!

thanks for you
