Weighting adjustment is a popular method for handling nonresponse in sample surveys. It consists of multiplying the sampling weights of the respondents by the inverse of their estimated response probabilities. Typically, response probabilities are estimated by fitting parametric models relating response occurrence and auxiliary variables. An alternative solution is the nonparametric estimation of them. The aim of this paper is to investigate, via simulation experiments, the small sample properties of kernel regression estimation of the response probabilities when auxiliary information consists in various mixed data type variables.

Abstract
Weighting adjustment is a popular method for handling nonresponse in sample surveys. It consists of multiplying the sampling weights of the respondents by the inverse of their estimated response probabilities. Typically, response probabilities are estimated by fitting parametric models relating response occurrence and auxiliary variables. An alternative solution is the nonparametric estimation of them. The aim of this paper is to investigate, via simulation experiments, the small sample properties of kernel regression estimation of the response probabilities when auxiliary information consists in various mixed data type variables.
