William J. Youden
William John Youden (April 12, 1900 – March 31, 1971) was an Australian-born American statistician who formulated new statistical techniques in statistical analysis and in design of experiments. He developed the "Youden square", an incomplete block design developed from a 1937 paper, "Use of Incomplete Block Replications in Estimating Tobacco Mosaic Virus". He also helped to introduce the concept of restricted randomization, which he called constrained randomization."Youden, William John." ''Complete Dictionary of Scientific Biography. 2008.''

Townsville
Townsville is a city on the north-eastern coast of Queensland, Australia. With a population of 180,820 as of June 2018, it is the largest settlement in North Queensland; it is unofficially considered its capital. Estimated resident population, 30 June 2018. Townsville hosts a significant number of governmental, community and major business administrative offices for the northern half of the state. Part of the larger local government area of the City of Townsville, it is in the dry tropics region of Queensland, adjacent to the central section of the Great Barrier Reef. The city is also a major industrial centre, home to one of the world's largest zinc refineries, a nickel refinery and many other similar activities. As of December 2020, $30M operations to expand the Port of Townsville are underway, which involve channel widening and installation of a 70-tonne Liebherr Super Post Panamax Ship-to-Shore crane, to allow much larger cargo and passenger ships to utilise the port.

Restricted Randomization
In statistics, restricted randomization occurs in the design of experiments and in particular in the context of randomized experiments and randomized controlled trials. Restricted randomization allows intuitively poor allocations of treatments to experimental units to be avoided, while retaining the theoretical benefits of randomization. For example, in a clinical trial of a new proposed treatment of obesity compared to a control, an experimenter would want to avoid outcomes of the randomization in which the new treatment was allocated only to the heaviest patients. The concept was introduced by Frank Yates (1948) and William J. Youden (1972) "as a way of avoiding bad spatial patterns of treatments in designed experiments." Example of nested data Consider a batch process that uses 7 monitor wafers in each run. The plan further calls for measuring a response variable on each wafer at each of 9 sites. The organization of the sampling plan has a hierarchical or nested structure: the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Rochester Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...

Philosophical Society Of Washington
Founded in 1871, the Philosophical Society of Washington is the oldest scientific society in Washington, D.C. It continues today as PSW Science. Since 1887, the Society has met regularly in the assembly hall of the Cosmos Club. In the Club's present location since 1951, the assembly hall is now called the John Wesley Powell auditorium. Meetings are roughly every other Friday, except in the summer. Meetings are free and open to the public. A lecture is given by a scientist at each meeting. In 1931, the Society established the ongoing Joseph Henry Lecture series. The lectures present speakers at who have reached the pinnacles of their respective fields, and in recent years have included Nobel laureates Baruch Blumberg, William D. Phillips, John C. Mather, and Craig Mello. History The Saturday Club In 1846, the Smithsonian Institution was founded and its Regents elected Joseph Henry as the Institution’s first Secretary.

Joint Statistical Meetings
The Joint Statistical Meetings (JSM) is a professional conference/academic conference for statisticians held annually every year since 1840 (usually in August).

American Statistical Association
The American Statistical Association (ASA) is the main professional organization for statisticians and related professionals in the United States. It was founded in Boston, Massachusetts on November 27, 1839, and is the second oldest continuously operating professional society in the US (only the Massachusetts Medical Society, founded in 1781, is older). The ASA services statisticians, quantitative scientists, and users of statistics across many academic areas and applications. The association publishes a variety of journals and sponsors several international conferences every year. Mission The organization's mission is to promote good application of statistical science, specifically to: * support excellence in statistical practice, research, journals, and meetings * work for the improvement of statistical education at all levels * promote the proper application of statistics * anticipate and meet member needs * use the discipline of statistics to enhance human welfare * seek opp ...

Youden's J Statistic
Youden's J statistic (also called Youden's index) is a single statistic that captures the performance of a dichotomous diagnostic test. Informedness is its generalization to the multiclass case and estimates the probability of an informed decision. Definition Youden's ''J'' statistic is : J = \text + \text -1 with the two right-hand quantities being sensitivity and specificity. Thus the expanded formula is: : J = \frac+\frac-1 The index was suggested by W.J. Youden in 1950 as a way of summarising the performance of a diagnostic test, however the formula was earlier published in Science by C.S.Pierce in 1884. Its value ranges from -1 through 1 (inclusive), and has a zero value when a diagnostic test gives the same proportion of positive results for groups with and without the disease, i.e the test is useless. A value of 1 indicates that there are no false positives or false negatives, i.e. the test is perfect. The index gives equal weight to false positive and false negative ...

Tobacco Mosaic Virus
''Tobacco mosaic virus'' (TMV) is a positive-sense single-stranded RNA virus species in the genus ''Tobamovirus'' that infects a wide range of plants, especially tobacco and other members of the family Solanaceae. The infection causes characteristic patterns, such as "mosaic"-like mottling and discoloration on the leaves (hence the name). TMV was the first virus to be discovered. Although it was known from the late 19th century that a non-bacterial infectious disease was damaging tobacco crops, it was not until 1930 that the infectious agent was determined to be a virus. It is the first pathogen identified as a virus. The virus was crystallised by W.M. Stanley. It has a similar size to the largest synthetic molecule, known as PG5 History In 1886, Adolf Mayer first described the tobacco mosaic disease that could be transferred between plants, similar to bacterial infections. In 1892, Dmitri Ivanovsky gave the first concrete evidence for the existence of a non-bacterial infect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
