We study the problem of testing for equality at a fixed point in
the setting of nonparametric estimation of a monotone function.The likelihood
ratio test for this hypothesis is derived in the particular case of interval
censoring (or current status data)and its limiting distribution is obtained.
The limiting distribution is that of the integral of the difference of the
squared slope processes corresponding to a canonical version of the problem
involving Brownian motion $+t^2$ and greatest convex minorants thereof.
Inversion of the family of tests yields pointwise confidence intervals for the
unknown distribution function.We also study the behavior of the statistic under
local and fixed alternatives.
