Tests for Changing Mean with Monotonic Power

Several widely used tests for a changing mean exhibit nonmonotonic power in finite samples due to “incorrect” estimation of nuisance parameters under the alternative. In this paper, we study the issue of nonmonotonic power in testing for changing mean. We investigate the asymptotic power properties of the tests using a new framework where alternatives are characterized as having “large” changes...

Monotonic Power in Tests for Changing Mean

Abstract. Many tests for a changing mean in a time series require the estimation of a long run variance. Recent research of Crainiceanu and Vogelsang (2001) suggests that tests involving a long run variance estimate exhibit non-monotonic power. We propose an estimate of long run variances that allows for a time varying mean. In this way, we are able to avoid non-monotonic power while still reta...

The power and size of mean reversion tests

The power of mean reversion tests has long been a tacit issue of the market efficiency literature. Early tests of market efficiency, as summarized in Fama Ž . 1970 , found no economically significant evidence of serial correlation in stock Ž . returns. However, Summers 1986 later suggested that this was because these tests lacked power: Summers suggested a model of AfadsB in which stock prices ...

Tests for One Exponential Mean

This program module designs studies for testing hypotheses about the mean of the exponential distribution. Such tests are often used in reliability acceptance testing, also called reliability demonstration testing. Results are calculated for plans that are time censored or failure censored, as well as for plans that use with replacement or without replacement sampling. We adopt the basic method...

Non-Inferiority Tests for One Mean

Paired data may occur because two measurements are made on the same subject or because measurements are made on two subjects that have been matched according to other variables. Hypothesis tests on paired data can be analyzed by considering the difference between the paired items as the response. The distribution of differences is usually symmetric. In fact, the distribution must be symmetric i...
