Hi Michael,
In all the masking process some of the variables were missed. Please find
the updated file.
Also here is the updated code: (i am removed one of the var as it had
missing information):
glm.fit= glm(survey ~ support_cat + region+ support_lvl+ skill_group+
application_area+ functional_a
Your example code refers to a variable which is not in your dataset
(repS) so I get an error message. If I assume repS is in fact rep_score
I get another variable not found (delivery_segmentation).
I am afraid that I am unable to sort that one out so this is going to
remain a mystery. I endors
Sure Burt, i will share the data after masking it. it isn't big

1. No, changing to factor will make no difference.
2. I think that most likely your problem is your model is not
estimable/your design matrix is singular. You should resolve this by
consulting with a local statistical expert or, if your data set is not
too large or confidential, posting your full
Hi Michael,
There is no output as the model does not generate any coefficients and
simply throws this error.
I hope you are not asking for a reproducible example.

Dear Shivi
Can you show us the output?
And please do not post in HTML as it will mangle your post into
unreadability.

Hi Team,
I am creating *my first* Logistic regression on R Studio. I am working on a
C-SAT data where rating (score) 0-8 is a dis-sat whereas 9-10 are SAT. As
these were in numeric form so i had as below created 2 classes:
new$survey[new$score>=0 & new$score<=8]<- 0
new$survey[new$score>=9]<- 1

I have gotten the this error before: "glm.fit: fitted probabilities
numerically 0 or 1 occurred"
and the problem was usually solved by combining one or more categories were
there were no observations.
I am now having this error show up for a variable that is continuous (not
categorical).

Dear ted, thanks for your help. Now, everything is more clear. I read
something about "linear separation" you mentioned, and my data set is very
suitable for this problem. But, there is a confusing question for me;
I can not controll the process adequately because of usage of bootstrap. So,

Dear Ellison,
Many thanks for your reply.
The information you typed is clear and now I know what to do. Your
suggestion about finding some coffee while running simulation is so good =)

There are two separate issues.
One is the appearance of fitted values at 0 or 1.
The other is the lack of convergence.
Hi all,
I am doing bootstrap with logistic regression by using glm function, and I
get the errors;
glm.fit: fitted probabilities numerically 0 or 1 occurred and
glm.fit: algorithm did not converge
I have read some things about this issue in the mailing list. I can guess
what was the problem. My

Hi,
could anyone explain to me what this warning message
exactly means and what the consequences are?
Is it due to the fact that there are very extreme
observations / outliers included or what is the reason
for it?
Thanks so much,
Werner
