NONPARAMETRIC BINARY REGRESSION WITH RANDOM COVARIATES
P. Diaconis D. Freedman
Abstract: The performance of Bayes’ estimates is studied under an assumption of
conditional exchangeability. More exactly, for each subject in a data set, let
be a vector of binary covariates and let be a binary response variable with
Here, is an unknown function, to be estimated from the data; the
subjects are independent, and the ’s are iid uniform. Define a prior distribution on as

covariates and for infinitely many Bayes’ estimates are consistent at all if
