1	Análise de regressão incorporando o esquema amostral / Regression analysis incorporating the sample design Figueiredo, Cléber da Costa 22 June 2004 (has links) Neste trabalho estudamos modelos lineares de regressão para a análise de dados obtidos de pesquisas amostrais complexas. Foram considerados aspectos teóricos e aplicações a conjuntos de dados reais por meio do uso do aplicativo SUDAAN e da biblioteca ADAC da linguagem R. Nas aplicações foram abordados os modelos de regressão normal e logística. Foram realizados também estudos comparativos dos métodos estudados com os que assumem que as observações são selecionadas segundo amostragem aleatória simples. / We have studied linear regression models for data analysis when the data set comes from a complex sampling survey. We have considered theoretical aspects and some applications utilizing the SUDAAN software and the ADAC library for R language. The applications involved the normal and logistic regression models. The studied methods were compared with those obtained from simple random samples. Amostragem Regressão Regression Sampling SUDAAN SUDAAN

3	A Logistic Regression Analysis of Utah Colleges Exit Poll Response Rates Using SAS Software Stevenson, Clint W. 27 October 2006 (has links) (PDF) In this study I examine voter response at an interview level using a dataset of 7562 voter contacts (including responses and nonresponses) in the 2004 Utah Colleges Exit Poll. In 2004, 4908 of the 7562 voters approached responded to the exit poll for an overall response rate of 65 percent. Logistic regression is used to estimate factors that contribute to a success or failure of each interview attempt. This logistic regression model uses interviewer characteristics, voter characteristics (both respondents and nonrespondents), and exogenous factors as independent variables. Voter characteristics such as race, gender, and age are strongly associated with response. An interviewer's prior retail sales experience is associated with whether a voter will decide to respond to a questionnaire or not. The only exogenous factor that is associated with voter response is whether the interview occurred in the morning or afternoon.
