GNU PSPP 1 Introdução

Pspp é uma ferramenta para análise estatística de dados simplificados. Ele lê os dados, analisa-os de acordo com os comandos providos, e escreve os resultados em um arquivo de listagem, para saída padrão de acordo com os comandos providos, ou para uma janela com uma janela de exibição gráfica. A linguagem aceita pelo pspp é similar àquelas aceitas pelos produtos de estatística SPSS. Os detalhes da linguagem do pspp serão dados depois nesse manual. Pspp produz tabelas e gráficos como saída, que podem ser ser produzidos em vários formatos; atualmente, ASCII, PostScript, PDF, HTML e DocBook são suportados. A versão atual do pspp, 0.10.2, é incomplete em termos termos de suporte ao procedimento estatístico. Pspp é um trabalho em andamento. Os autores esperam apoiar todas as características nos produtos que pspp irá substituir, eventualmente. Os autores saúdam perguntas, comentários, doações, e envois de código. Leia Capitulo 20 [Enviando Relatórios de Bugs], página 178, para instruções sobre contatar os autores.
