logistic regression in R - changing defaults
...ice in changing 2 defaults in a logistic regression.
1. It looks like the first category is the reference category? In the
following syntax 'where' has 4 levels, how can I make the reference
category the third category?
model<- glm(cbind(sucesses, failures) ~ where + who + firstep + dxnarrow +
age + sex + medyear, family = binomial, data=life.use)
model
2. Is it possible to round results to 4 decimal points? If so, what syntax
is required?
Any assistance is appreciated,
Bob Green
