New semiparametric and nonparametric bootstrap tests for Spearman's rho
MetadataShow full item record
In this paper we propose two bootstrap-based tests for Spearman's rho. The first is a semiparametric test based on copulas, while the second is a nonparametric test. The efficiency of the tests are investigated by means of a Monte-Carlo study. It is found that they perform very satisfactorily as far as size and power are concerned.
