Growth data and longitudinal data in general are often of an ordinal nature. For example, developmental stages may be classified into ordinal categories and behavioral variables repeatedly measured by discrete ordinal scales. Consider the data set presented in Table 15.1. This table contains information on marijuana use taken from five annual waves (1976–80) of the National Youth Survey (Elliot...

The personal name aliases are extremely significant in information retrieval to retrieve complete information about a personal name from the web, as some of the web pages of the person may also be referred by his or her alias name / nick name / real name. There is a rapid growth in people searching where the personal name aliases are concerned. We proposed a pattern generator which includes aut...

In this paper, we propose a new counting scheme for m × n contingency tables. Our scheme is a modification of Dyer and Greenhill’s scheme for two rowed contingency tables [5]. We can estimate not only the sizes of error, but also the sizes of the bias of the number of tables obtained by our scheme, on the assumption that we have an approximate sampler. key words: counting, approximation, #P-com...

In this paper we are proposing a general framework for the analysis of the complete set of log Odds Ratios (ORs) generated by a two-way contingency table. Starting from the RC (M) association model and hypothesizing a Poisson distribution for the counts of the two-way contingency table we are obtaining the weighted Log Ratio Analysis that we are extending to the study of log ORs. Particularly w...

This paper presents and compares approaches of estimating true area on the ground and calibrating quantitative errors of area estimate on categorical maps from the contingency table. Results directly estimated from the contingency table and those from two calibration methods were compared on two maps of 10 different land cover classes with known errors between them. The estimated true area perc...

! Abstract The predominant normative justification for research on economic voting has been its essential role in shaping democratic accountability. A systematic examination of this literature reveals, however, that economic voting is highly contingent on two critical moderating factors: voters themselves and the political context in which they make judgments. The trend toward a better and more...

This paper looks at the interaction of poverty, fertility preferences and family planning practice in the Philippines using the series of nationally representative Family Planning Surveys conducted annually since 1999 augmented by census and other survey data. Its contribution lies on providing recent and nationally representative empirical evidence on the long running but largely unresolved de...

Seventy-five years ago, Yates (1934) presented an article introducing his continuity correction to the χ test for independence in contingency tables. The paper also was one of the first introductions to Fisher’s exact test. We discuss the historical importance of Yates and his 1934 paper. The development of the exact test and continuity correction are studied in some detail. Subsequent disputes...

We describe new results for sharp upper and lower bounds on the entries in multi-way tables of counts based on a set of released and possibly overlapping marginal tables. In particular, we present a generalized version of the shuttle algorithm proposed by Buzzigoli and Giusti that computes sharp integer bounds for an arbitrary set of fixed marginals. We also present two examples which illustrat...

In this work we study several types of diagonal-effect models for two-way contingency tables in the framework of Algebraic Statistics. We use both toric models and mixture models to encode the different behavior of the diagonal cells. We compute the invariants of these models and we explore their geometrical structure.
