          Exploratory Longitudinal Data Analysis
          Di Cook, Iowa State University}  
 
    Longitudinal data is collected by measuring the same individual
    multiple times. The measurements for each individual may be collected
    at different times, and for a differing number of time points. In
    contrast to cross-sectional studies, longitudinal data provides the
    opportunity to study individual trends as well as average trends, and
    this is a most interesting challenge for statistical analysis.

    This talk will follow up on the Colloquium talk. We'll explain
    exploratory approach to longitudinal data analysis, and how this
    differs, conceptually, from a purely modelling approach.  Successful
    exploration is dependent on setting up the data structures that allow
    data tables to be linked for exploring raw data, fitted values, and
    model diagnostics, and how the calculations are linked to the
    graphics.  We'll explain how this is done using R, rggobi and
    GGobi. There are some curious observations about the models for the
    workforce experience data, to look forward to.
