Dear all,
I have an outcome y dichotomous (0/1) and a continuous predictor X1

I use
logit y X1
I predict
and then I use the lowess smooth curve

I have a confusion about the lowess.

I am not sure if the lowess fits smooth successive non paramteric regression (Y X1) for successive small intervals of X1 (starting with the smallest values of X1), and then produces a smooth option of the predicted probabilities

Or if it fits successive logistic regression models followed by a smooth graph of these probabilities of these models

Please can you advise on this question?

Thanks a lot for your useful comments
