We look forward to seeing you at our April meeting.
Talk Outline: Complex designs are common in survey data. In practice, collecting random samples from populations is costly and impractical. The data are often non-independent or disproportionately sampled, and violate the typical assumption of independent and identically distributed samples (IID).
The Survey package in R (written by Thomas Lumley) is a powerful tool that incorporates survey designs to the data. It implements standard statistics, from linear models to survival analysis with the corresponding mathematical corrections.
This talk will provide an introduction to survey statistics and the Survey package. There will be a brief overview of complex designs and some of the theory behind their analysis, followed by a demonstration using the Survey package.
About our speaker: Sebastián Duchêne is a Ph.D. candidate at The University of Sydney, based at the Molecular Phylogenetics, Ecology, and Evolution Lab.His broad area of research is virus evolution.
His current projects include an R package for evolutionary analysis, and the development of statistical models for molecular epidemiology and he is a reviewer for the PLoS ONE academic journal for evolution and bioinformatics. Before coming to Sydney, he was a data analyst at the National Oceanic and Atmospheric Administration (NOAA) in the USA.
