Applications of nonparametric methods in natural resource surveys Jean Opsomer Colorado State University In many surveys of natural resources, auxiliary information is readily available and can be used to develop models to assist in estimation of finite population quantities. Over the past few years, several collaborators and I have applied nonparametric methods in surveys in agriculture, forestry and aquatic resource assessment. I will describe some of these applications and illustrate the advantages of the nonparametric approaches over the more traditional parametric ones. Nonparametric estimation for survey data remains a relatively new area with plenty of opportunities for innovative and practically useful research.
