Full Bayesian Empirical Likelihood Significance Test for Equality Of Medians
This paper discusses the empirical likelihood ratio test for testing equality of medians of two distributions. Yu et al. (2011) proposed four forms of empirical likelihood ratio test for testing this hypothesis and one of them is based on the pooled sample median. The asymptotic distribution of the test statistic as derived in Yu et al (2011) differ from the one obtained in Nimbalkar and Rajars...
متن کاملAn equality test across nonparametric regressions
A procedure for testing equality across nonparametric regressions is proposed The proce dure allows for any dimension of the explanatory variables and for any number of subsamples We consider the case of random explanatory variables and allow the designs of the regressors and the number of observations to di er across subsamples The division into subsamples is de ned through a variable C which ...

متن کاملA Nonparametric Two-Sample Wald Test of Equality of Variances
We develop a test for equality of variances given two independent random samples of observations. The test can be expected to perform well when both sample sizes are at least moderate and the sample variances are asymptotically equivalent to the maximum likelihood estimators of the population variances. The test is motivated by and is here assessed for the case when both populations sampled are...
متن کاملNonparametric estimation of conditional medians for linear and related processes
We consider nonparametric estimation of conditional medians for time series data. The time series data are generated from two mutually independent linear processes. The linear processes may show long-range dependence. The estimator of the conditional medians is based on minimizing the locally weighted sum of absolute deviations for local linear regression. We present the asymptotic distribution...
