B. Rajagopalan et al., EVALUATION OF KERNEL DENSITY-ESTIMATION METHODS FOR DAILY PRECIPITATION RESAMPLING, Stochastic hydrology and hydraulics, 11(6), 1997, pp. 523-547
Kernel density estimators are useful building blocks for empirical sta
tistical modeling of precipitation and other hydroclimatic variables.
Data driven estimates of the marginal probability density function of
these variables (which may have discrete or continuous arguments) prov
ide a useful basis for Monte Carlo resampling and are also useful for
posing and testing hypotheses (e.g. bimodality) as to the frequency di
stributions of the variable. In this paper, some issues related to the
selection and design of univariate kernel density estimators are revi
ewed. Some strategies for bandwidth and kernel selection are discussed
in an applied context and recommendations for parameter selection are
offered. This paper complements the nonparametric wet/dry spell resam
pling methodology presented in Lall et al. (1996).
