Sequential effects in successive ratio estimation.
Sequential effects are examined in four successive ratio estimation (RE) experiments. The procedure in successive RE is identical to that for magnitude estimation (ME), but the task in successive RE is to estimate the ratio of the current to the previous sensation magnitude, and not the separate magnitudes of the sensations. A positive stimulus context effect was found in successive RE for seve...
متن کاملSequential change-point detection based on direct density-ratio estimation
Change-point detection is the problem of discovering time points at which properties of time-series data change. This covers a broad range of real-world problems and has been actively discussed in the community of statistics and data mining. In this paper, we present a novel nonparametric approach to detecting the change of probability distributions of sequence data. Our key idea is to estimate...
متن کاملQuantile Estimation in Successive Sampling
In successive sampling on two occasions the problem of estimating a finite population quantile has been considered. The theory developed aims at providing the optimum estimates by combining (i) three double sampling estimators viz. ratio-type, product-type and regression-type, from the matched portion of the sample and (ii) a simple quantile based on a random sample from the unmatched portion o...
متن کاملEstimation of population variance in successive sampling
This paper proposes a class of estimators of finite population variance in successive sampling on two occasions and analyzes its properties. Isaki (J Am Stat Assoc 78:117– 123, 1983) motivated to consider the problem of estimation of finite population variance in survey sampling, and its extension to the case of successive sampling is much interesting, and the theory developed here will be help...
متن کاملVisual pattern matching: Effects of size ratio, complexity, and similarity in simultaneous and successive matching
An experiment on mental transformation of size, in pairwise comparison of simultaneously or successively presented ®gures with respect to shape, is reported. Regardless of type of presentation (simultaneous vs. successive), ®gural complexity, and similarity within pairs of dierent-shaped ®gures, median latencies of both same and dierent responses were approximately linearly increasing functio...
