Careers Day in Statistics Saturday, March 1 2009 Statistics Careers Day Southern California Chapter of the American Statistical Association
The panelists for the Statistics Careers Day are:
The Southern California Chapter of the American Statistical Association presents
The 28th Annual Workshop in Applied Statistics
Department of Economics, University of California, Davis
ABSTRACT
This
workshop will cover regression models for count data, such as data on the
number of doctor visits. Both econometrics methods that view counts as one
example of nonlinear regression, and statistics methods that view counts as
one example of generalized linear models, will be presented. The four sessions
will cover, respectively, basic cross-section methods, more advanced
cross-section methods, time-series methods and panel-data methods.

May 30: SCASA’s 4th Annual PosterComp at City of Hope
Info on Poster Competion
SCASA’s 4th annual poster sessions competition for AP statistics students will
be held as a separate event on May 30, 2009, at City of Hope National Medical
Center in Cooper Auditorium. Chapter members are needed to help with the judging
which is a rewarding experience as you will interview enthusiastic students on
their statistical projects in a poster session format. For this generation of
college graduates, many students may be getting their first and only formal
training in statistics in the high school AP stat class. This is your chance to
help insure that this generation sees statistics as an important and vital
applied area with interested, engaged professionals.
Please contact Rodney Jee for more

Abstracts for Talks
Exploring the housing crisis with ggplot2 and plyr.
ggplot2 is a new data visualization package for R that uses the insights from Leland Wilkison's Grammar of Graphics to create a
powerful and flexible system for creating data graphics. Practically, ggplot provides beautiful, hassle-free plots, that take care of fiddly
details like drawing legends.
In this talk you'll see ggplot2 in action, exploring a dataset of nearly half a million house sales in the Bay area. I'll start with the
basics, histograms and scatterplots, and then discuss how these plots can be enhanced with aesthetics and facetting to explore deeper into
the data, answering progressively more complicated questions. Graphics work best in conjunction with other analytic tools, so I'll
also show you how the plyr package can be used to create rich summary statistics, exploring how the housing bubble has effected cities in
the bay area differently. I'll connect these summaries to census data and speculate on who the bubble has affected most.
The Layered Grammar of Graphics
In this talk, I'll introduce you to the formalism that underlies ggplot2, the layered grammar. You'll learn about the pieces that make
up the grammar (data, aesthetics, layers, geoms, stats, position adjustments, coordinate systems and facetting) and how they all fit
together. In particular, I'll focus on plots that are difficult to describe with other graphics systems, showing the expressive power of
the grammar and how it allows us to move beyond canned graphics routines. To illustrate the flexibility of the graphic, I'll show some
recreations of famous plots, including Minard's famous "Napoleon's march".
The layered grammar builds on Wilkinson's "Grammar of Graphics" (in turn building on earlier work by Bertin) and you'll learn about why a
new grammar is needed and some of the advantages and disadvantages of embedding a graphical grammar within another programming language.
