glm.fit: fitted probabilities numerically 0 or 1 occurred for a continuous variable?
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).
What could be the cause of this for a continuous variable??
Thanks,
Nick

logistic regression - glm.fit: fitted probabilities numerically 0 or 1 occurred
Sorry if this is a duplicate: This is a re-post because the pdf's mentioned
below did not go through.
Hello,
I'm new'ish to R, and very new to glm. I've read a lot about my issue:
Warning message:

glm.fit: "fitted probabilities numerically 0 or 1 occurred"
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

regression
Hi dear all,
suppose that s is a statistic code;
i have a matrix (x) which has 7 columns (1=x1,2=x23=x3,4=x4,5=x5,6=x6
and7=y)
and has 20 rows. i want to do linear reggression like
reg<-lm(x[,7]~1+x[,1]+x[,2]+.......+x[,6])
but i want to do delete i th row for nrows times and create regression model
like above and compute each models' "s" statistics and list them. but i

Robust Statistics for Outlier Detection
Hi Dear All,
Can someone give me a suggestion about which robust statistics are most
appropriate for outlier detection in linear models, and is available with R
?
Thanks for any idea.

delete-d jackknife
Hi dear all,
Can aynone help me about delete-d jackknife
usually normal jackknife code for my data is:
n <- nrow(data)
y <- data$y
z <- data$z
theta.hat <- mean(y) / mean(z)
print (theta.hat)
theta.jack <- numeric(n)
for (i in 1:n)
theta.jack[i] <- mean(y[-i]) / mean(z[-i])
bias <- (n - 1) * (mean(theta.jack) - theta.hat)
print(bias)
but how i can apply delete-d jackknife

setting enviroment variable
I have a ror project which has been productized. There are several web
sites in one ror project
I need to set an "enviroment variable" to run different sites, can I do
that using mongrel? I tried to use mongrel''s -S option and set the
enviroment variable in that file but it seems mongrel runs that file
after it calls enviroment.rb
I also used apache''s

the server is using CentOS 7 and that is the package that comes through

manually as that could cause other compatibility issues? is there

Why unique(sample) decreases the performance ?
Hi,
I' am interested in differences between sample's result when samples consist
of full elements and consist of only distinct elements. When sample consist
of full elements it take about 120 sec., but when consist of only distinct
elements it take about 4.5 or 5 times more sec. I expected that opposite of
this result, because unique(sample) has less elements than full sample. Code

Fitted probabilities in conditional logit regression
Dear R-help,
I'm doing conditional logit regression for a discrete choice model.
I want to know whether there's a way to get the fitted probabilities. In
Stata, "predict" works for clogit, but it seems that in R "predict" does
not.
Thank you very much!
Best wishes.
Sincerely,
Min

Fitted probabilities from glmmPQL?
Hello All,
Specifying 'type = "response"' when using predict() on a
model fit using glm(...,family="binomial") returns fitted
probabilities.
Is it possible to get the same from a model object
fit using glmmPQL() ?
Thanks in advance,
Rob

Range in probabilities of a fitted lrm model (Y~X)
Dear R-list,
Is there a function or technique by which the probability (or log odds)
range of a logistic model (fit <- lrm(Y~X)) can be derived?
The aim is to obtain min & max of the estimated probabilities of Y.
Could summary.Design() be used for that or is there another method/trick?
Thanks,
Jan

SE of difference in fitted probabilities from logistic model.
I am fitting a logistic binomial model of the form
glm(y ~ a*x,family=binomial)
where a is a factor (with 5 levels) and x is a continuous predictor.
To assess how much ``impact'' x has, I want to compare the fitted
success probability
when x = its maximum value with the fitted probability when x = its
mean value.
(The mean and the max are to be taken by level of the factor
