Hi guys, I have a trouble to solve the specificity and senstitivity
for a logistic regression model. I really need your help, would you
please help me out? :) Thank you!!
This is the model I constructed:
>model=glm(Status ~ Gender.compl+ X2.4.times.per.month+

seems wrong somewhere, w
Hi guys,
I will be very grateful if you guys can do me a little favor on R. I am
calculating the sensitivity and specificity for a 2*2 matrix, such as
t
01
0 1427 110
1 271 166
My codes are: sens <- function(ct) { ct[2,2] / sum(ct[,2]) }
spec <- f
