Karl Pearson

Karl Pearson (Londres, 27 de março de 1857 — 27 de abril de 1936) foi um grande contribuidor para o desenvolvimento da estatística como uma disciplina científica séria e independente. Foi o fundador do Departamento de Estatística Aplicada na University College London em 1911; foi o primeiro departamento universitário dedicado à estatística em todo o mundo.

Contribuições para a estatística

O trabalho de Pearson foi muito abrangente na ampla aplicação e desenvolvimento da estatística matemática, e abrangeu os domínios da biologia, epidemiologia, antropometria, medicina e história social. Em 1901, junto com Weldon e Francis Galton fundou a revista Biometrika cujo objeto era o desenvolvimento da teoria estatística. Ele editou esta revista até a sua morte. Ele também fundou a revista Annals of Eugenics (agora Annals of Human Genetics), em 1925.

O pensamento de Pearson fundamentou muitos dos métodos estatísticos "clássicos" que são de uso comum atualmente. Algumas de suas principais contribuições são:

• Regressão linear e correlação - Pearson foi fundamental no desenvolvimento desta teoria. Um de seus clássicos conjuntos de dados (inicialmente recolhidos por Galton) envolve a regressão da altura dos filhos em relação à de seus pais. Pearson construiu um modelo de 3-dimensional com este conjunto de dados para ilustrar as ideias. O coeficiente de correlação produto-momento de Pearson é nomeado assim como homenagem a ele, foi a primeira medida de força de associação a ser introduzido em estatística.
• Classificação das distribuições - O trabalho de Pearson sobre classificação das distribuições probabilidade constitui a base para um ampla para a teoria moderna estatística, em particular, a família exponencial de distribuições é fundamental para a teoria do modelo linear generalizado.
• Teste Chi-quadrado de Pearson - Um tipo particular de teste qui-quadrado, um teste de significância estatística.
• Coeficiente de correlação e dois coeficientes de assimetria.^[1]
