One of the main principles in a design of experiment is to use blocking factors whenever it is possible. On the other hand, if the blocking information is not precisely defined and subjective in nature, it is usually discarded. This paper introduces a new design that utilizes available subjective information on experimental units to create artificial blocking factors and develops a rank-sum test to test the difference between two population medians.

A bibliography on the subject of mathematics is presented which includes the book "Complex Hyperbolic Structures on Disc Bundles Over Surfaces," by N. Gusevskii, "The Geometry of Discrete Groups," by A. F. Beardon, and "Geometrical Fniteness for Hyperbolic Groups," by B. H. Bowditch.

Chapter 56 of the book "Health Systems Performance Assessment" is presented. It discusses the use of the dichotomous variant of the hierarchical ordered probit (DIHOPIT) model in measuring the permanent income of respondents in a health survey. Some of the variables used to measure permanent income include age of household, number of household adults and occupation of household head. Statistical output from a DIHOPIT survey of Pakistani and Peruvian households is presented.

Chapter 8 of the book "Injury Chart Book" is presented. It presents data on suicide worldwide. It states that suicide refers to the death arising from an act inflicted upon oneself with the intent to kill oneself. It mentions that in 2000, about 815,000 people worldwide committed suicide. It emphasizes that 86 percent of all suicides occurred in the low- and middle-income countries.

Chapter 7 of the book "Injury Chart Book" is presented. It presents data on interpersonal violence. A definition of interpersonal violence is mentioned. It states that in 2000, about 520,000 people worldwide died due to interpersonal violence. It also emphasizes that 95 percent of homicides occurred in the low- and middle-income countries.

Chapter 6 of the book "Injury Chart Book" is presented. It presents data on poisoning accidents. It states that the data cover all unintentional poisoning-related deaths and non-fatal outcomes due to exposure to noxious substances. It states that in 2000, about 315,000 people worldwide died due to unintentional poisoning.

Chapter 5 of the book "Injury Chart Book" is presented. It presents data on fall-related injuries. It mentions that the chapter does not cover falls from animals, burning buildings and transport vehicles as well as falls into fire, water and machinery. It states that in 2000, about 283,000 people worldwide died due to falls.

Chapter 3 of the book "Injury Chart Book" is presented. It presents data on fire-related burns. A definition of a burn is mentioned. The data presented refer to fire-related burns only, and do not cover burns due to contact with hot substances or skin injuries due to ultraviolet radiation, radioactivity, electricity or chemicals.

Chapter 2 of the book "Injury Chart Book" is presented. It presents data on road traffic injuries, including global road traffic injury mortality, road traffic injury rates in World Health Organization regions by age group and sex as of 2000 and age distribution of global road traffic injury mortality as of 2000.

Chapter 4 of the book "Injury Chart Book" is presented. It presents data on drowning accidents. According to the World Health Organization International Classification of Diseases, all unintentional drowning and submersions are classified as drowning deaths. It states that about 450,000 people drowned worldwide in 2000.

Chapter 15 of the book "The Problem of Evil: An Intercultural Exploration" is presented. The author discusses statistics as to the extent of evil behavior among average workers such as time theft. He focuses on the incidence of white collar crimes and the problem of the phantom employees who willfully waste or squander their paid working hours. He also calls for a production of a system of values which is acceptable to all diverse groups as a means of reinstating basic values worldwide.

The article presents notes regarding health-related statistics for the 51 Member States of the World Health Organization European Region published in "Atlas of Health in Europe." The author states that the mortality rates used in the book cover those representing the working age. The author also mentions that death rates provided in the statistics are age-standardized death rates.

Heart Rate Variability (HRV) contains abundant information of cardiovascular regulation, which has been used as a non-invasive method to evaluate the function status of cardiovascular system. In this work, we mainly analyzed a non-linear parameter--correlation dimension (CD) extracted from different frequency domains of 24h HRV. Coronary heart disease (CHD) patient and healthy control were studied as contrast, and 24h HRV data recorded by Holter in clinic and from MIT-BIH Database was analyzed. The whole 24h data was respectively divided to four sections in time scale. CD was extracted from HRV before and after wavelet decomposition in four time sections. Results indicated the curve of CD from HRV in VLF is similar to that from HRV before wavelet decomposition. This verified most non-linear information was contained in VLF of HRV reported by other researchers. HRV signals in VLF from CHD patient group and control group were primarily studied. Average CD value in the third time section from healthy control was a little larger, which probably indicated in the afternoon the complexity was a bit higher in cardiovascular system of healthy control. The conclusion needs further study and statistic analysis to support. [ABSTRACT FROM AUTHOR]

A discussion of relative risk is presented. It defines relative risk as the probability of an outcome in individuals exposed to a particular factor or condition divided by the probability of that outcome in individuals not exposed. The characteristics, preclinical relevance and the relevance of relative risk to humans are discussed, as well as the significance of relative risk analyses in risk assessment.

A definition of the term "repeated measures design" is presented. It refers to an experimental design in which each subject is measured at multiple time points. Measures over time within a subject will be correlated with one another and it is necessary to incorporate this into the analysis.

A definition of the term "nonparametric statistics" is presented. It refers to the set of statistical techniques that does not make assumption regarding the underlying distribution of data.

The article presents a definition of the term "analysis of covariance." It refers to a set of procedures similar to the analysis of variance, but where statistical methods are used to adjust for the effects of a variable which is correlated with the dependent variable.

The article presents a definition for the term "concordance," a statistical term used to determine the probability of correctly identifying a compound which is either immunosuppressive or not immunosuppressive.
