A Sampling Approach to Ultra-fast Object Location
Real-Time Imaging, 2001Summary: This paper examines how sampling can form the basis for ultra-fast location of objects in digital images. The body-based sampling approach that is adopted is unusual in that detection speed is improved for larger objects. The fact of sampling leads initially to more imprecise object location, this poses the problem of finding methods by which ...

The Use of Network Sampling for Locating the Seriously III
Medical Care, 1988Network sampling, based on the experience of conducting the large-scale 1986 Robert Wood Johnson Foundation National Access to Health Care Survey, was shown to be a viable alternative to more conventional procedures for oversampling persons with a low incidence and prevalence of health conditions. The network sampling approach was a more economical and

Sampling Hard-to-Locate Populations
2017This chapter discusses the challenges that researchers face when conducting surveys on hard-to-survey populations. It begins with an overview of the various conditions that can make it difficult to include some populations in studies or surveys. This includes the population’s being hard to identify and locate or hard to persuade or interview and even ...

Two samples differing in location
1989In this chapter we’ll develop the mathematical foundation and the asymptotic properties of suitable rank tests with estimated scores for the two-sample problem. We restrict the discussion to the two-sample model in order to present the basic ideas in the simplest form. The corresponding k -sample model will be treated in Section 4.2.

Sampling dark networks to locate people of interest
Social Network Analysis and Mining, 2018Dark networks, which describe networks with covert entities and connections such as those representing illegal activities, are of great interest to intelligence analysts. However, before studying such a network, one must first collect appropriate network data.

Sampling scheme for locating two-dimensional parts
International Journal of Manufacturing Research, 2007Car manufacturers often need to compare and choose a car hood fixture that gives a good quality fitting between the hood and the body. The good quality hood fitting is usually defined as a constant-width gap from the car body and is typically evaluated from Coordinate Measuring Machine (CMM) data collected from the hood's surface after placement ...

Several-sample location problem
2010In this chapter we consider tests and estimates based on identity, spatial sign, and spatial rank scores in the several independent samples setting. We get multivariate extensions of the Moods test, Wilcoxon-Mann-Whitney test, Kruskal- Wallis test and the two samples Hodges-Lehmann estimator.

Location estimates for single samples
1989In Chapters 2 to 7 we consider data that are either measurements or ranks specifying order of magnitude or preference. The latter are called ordinal data. Chapters 2 and 3 are devoted to single samples. Most practical problems involve comparison of, or studying relations between, several samples, but many basic nonparametric notions are applicable also

Tests for Location with k Samples and Censored Data
Biometrika, 1987Tests which are specific for location are developed in the k-sample situation with right-censored data. The tests are based on general estimating functions, and do not require full parametric assumptions for large samples, but in general they are not based only on ranks. One class of tests allows shapes to differ in the k populations, and includes as a
