Subject: [R] local regression using loess

Hi, All,

I have a dataset with binary response ( 0 and 1) and some numerical
covariates. I know I can use logistic regression to fit the data. But I want
to consider more locally. So I am wondering how can I fit the data with
'loess' function in R? And what will be the response: 0/1 or the probability
in either group like in logistic regression?

-- Neither. Loess is an algorithm that smoothly "interpolates" the data. It
makes no claim of modeling the probability for a binary response variable.
