We establish pointwise and uniform large deviations limit theorems of
Chernoff-type for the non-parametric kernel density estimator based on
a sequence of independent and identically distributed random variable
s. The limits are well-identified and depend upon the underlying kerne
l and density function. We derive then some implications of our result
s in the study of asymptotic efficiency of the goodness-of-fit test ba
sed on the maximal deviation of the kernel density estimator as well a
s the inaccuracy rate of this estimate.
