Statistical Graphics for Survey Weights

Ponderación de la muestra se utilizan para corregir las diferencias conocidas entre la muestra y la población debido al diseño de la muestra, la falta de respuesta, la falta de cobertura, y otros factores. Sin embargo, consideraciones prácticas a menudo resultan en pesos que no se han construido de una manera sistemática. Los métodos gráficos pueden ser útiles en la comprensión de ponderaciones...

Statistical Graphics of Pearson Residuals in Survey Logistic Regression Diagnosis

Survey data logistic regression analysis, as computationally available in SAS SURVEYLOGISTIC procedure, has been widely conducted in survey research practice. A set of diagnostic statistics in the procedure, borrowed from the logistic regression in generalized linear models, is used for model assessment. However, for survey data, the statistical underpinnings of these statistics may need to be ...

C4.1 Interactive Statistical Graphics

Examining data using graphical tools, such as histograms, bar charts, quantile plots, scatterplots and other statistical graphics, is a necessary part of any serious analysis effort. Statistical graphics are typically most useful at two stages of an analysis. Initially, plots are useful for data cleansing [cross-ref. C2.1] where unusual sets of values can be investigated, attribute distribution...
