Nathan Mantel
Nathan Mantel (February 16, 1919 – May 25, 2002) was an American biostatistician best known for his work with William Haenszel, which led to the Mantel–Haenszel test and its associated estimate, the Mantel–Haenszel odds ratio. The Mantel–Haenszel procedure and its extensions allow data from several sources or groups to be combined while avoiding confounding. He spent much of his career working for the National Cancer Institute. During his career, he published over 380 academic papers. Later in his life, Mantel was known for defending the tobacco industry against claims that passive smoking was harmful.

Pittsburgh Post-Gazette
The ''Pittsburgh Post-Gazette'', also known simply as the PG, is the largest newspaper serving metropolitan Pittsburgh, Pennsylvania. Descended from the ''Pittsburgh Gazette'', established in 1786 as the first newspaper published west of the Allegheny Mountains, the paper formed under its present title in 1927 from the consolidation of the ''Pittsburgh Gazette Times'' and ''The Pittsburgh Post''. The ''Post-Gazette'' ended daily print publication in 2018 and has cut down to two print editions per week (Sunday and Thursday), going online-only the rest of the week. In the 2010s, the editorial tone of the paper shifted from liberal to conservative, particularly after the editorial pages of the paper were consolidated in 2018 with '' The Blade'' of Toledo, Ohio. After the consolidation, Keith Burris, the pro-Trump editorial page editor of '' The Blade'', directed the editorial pages of both papers.

Mathematicians From New York (state)
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, structure, space, models, and change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman mathematician recorded by history was Hypatia ...

Scientists From New York City
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

Logrank Test
The logrank test, or log-rank test, is a hypothesis test to compare the survival distributions of two samples. It is a nonparametric test and appropriate to use when the data are right skewed and censored (technically, the censoring must be non-informative). It is widely used in clinical trials to establish the efficacy of a new treatment in comparison with a control treatment when the measurement is the time to event (such as the time from initial treatment to a heart attack). The test is sometimes called the Mantel–Cox test. The logrank test can also be viewed as a time-stratified Cochran–Mantel–Haenszel test. The test was first proposed by Nathan Mantel and was named the ''logrank test'' by Richard and Julian Peto. Definition The logrank test statistic compares estimates of the hazard functions of the two groups at each observed event time. It is constructed by computing the observed and expected number of events in one of the groups at each observed event time and ...

Passive Smoking
Passive smoking is the inhalation of tobacco smoke, called secondhand smoke (SHS), or environmental tobacco smoke (ETS), by persons other than the intended "active" smoker. It occurs when tobacco smoke enters an environment, causing its inhalation by people within that environment. Exposure to secondhand tobacco smoke causes disease, disability, and death. The health risks of secondhand smoke are a matter of scientific consensus. These risks have been a major motivation for smoke-free laws in workplaces and indoor public places, including restaurants, bars and night clubs, as well as some open public spaces. Concerns around secondhand smoke have played a central role in the debate over the harms and regulation of tobacco products. Since the early 1970s, the tobacco industry has viewed public concern over secondhand smoke as a serious threat to its business interests. Harm to bystanders was perceived as a motivator for stricter regulation of tobacco products. Despite the indust ...

Tobacco Industry
The tobacco industry comprises those persons and companies who are engaged in the growth, preparation for sale, shipment, advertisement, and distribution of tobacco and tobacco-related products. It is a global industry; tobacco can grow in any warm, moist environment, which means it can be farmed on all continents except Antarctica. According to the WHO Framework Convention on Tobacco Control, the "tobacco industry" encompasses tobacco manufacturers, wholesale distributors and importers of tobacco products. This evidence-based treaty expects its 181 ratified member states to implement public health policies with respect to tobacco control "to protect present and future generations from the devastating health, social, environmental and economic consequences of tobacco consumption and exposure to tobacco smoke." Tobacco, one of the most widely used addictive substances in the world, is a plant native to the Americas and historically one of the most important crops grown by Ameri ...
