Smoothed nonparametric two-sample tests
Taku Moriyama, Yoshihiko Maesono
We propose new smoothed median and the Wilcoxon's rank sum test. As is pointed out by Maesono et al.(2016), some nonparametric discrete tests have a problem with their significance…
A new method of joint nonparametric estimation of probability density and its support
Taku Moriyama
In this paper we propose a new method of joint nonparametric estimation of probability density and its support. As is well known, nonparametric kernel density estimator has "bounda…
A new kernel estimator of hazard ratio and its asymptotic mean squared error
Taku Moriyama, Yoshihiko Maesono
The hazard function is a ratio of a density and survival function, and it is a basic tool of the survival analysis. In this paper we propose a kernel estimator of the hazard ratio…
Smoothed nonparametric tests and their properties
Yoshihiko Maesono, Taku Moriyama, Mengxin Lu
In this paper we propose new smoothed sign and Wilcoxon's signed rank tests, which are based on a kernel estimator of the underlying distribution function of data. We discuss appro…
