'A Random Walk Through Climate Change'
This talk walks through some of the statistical issues in climate change
studies. We start on a global level, examining the classic
Hansen-Lebedeff temperature series for possible trends. Issues of
long-memory regression errors and non-linear regression responses are
considered. We then move to a more local level, considering temperature
changes in the United States over the last 150 years. Issues of station
site changes (changepoints), temporal correlations, and data collection
frequency (yearly vs. monthly) are the focus.

'Connecting the Dots: Using Exponential
Random Graph Models to Predict the
Location of Ties in Networks'
Recent advances in statistical models for networks, exponential random
graph models, are outlined and applied to the question of predicting the
presence of a tie between two nodes i and j in a network. These models
allow the presence/absence of a tie to be affected by the local
neighborhood of ties surrounding a particular couple, i and j, and by
the attribute similarity or dissimilarity of i and j. Arenas for
application include the Polish political opposition movement, the US
Senate, and the Paris Metro.
