I have been trying to run a logistic regression using a number of
studies.
Below is the syntax, error message & data.
Any advice regarding what I am doing wrong or solutions are
appreciated,
regards
Bob Green
logreg <- read.csv("c:\\logregtest.csv",header=T)
attach(logreg)
names(logreg)
[1] "medyear" "where" "who" "dxbroad" "firstep"
"standard"

model <- glm(cbind(successes, failures) ~medyear + age + sex +
where +
who + dxbroad + firstep + standard, family=binomial, data=Dataset)
Error in inherits(x, "data.frame") : object "Dataset" not found
