The sixth annual Penn State Summer School in Statistics for Astronomers will be held at Penn State. The main part of the School is a 6-day course (June 7-12, 2010) in fundamental statistical inference designed to provide researchers and graduate students in the physical sciences with a strong conceptual foundation in modern statistics. We develop a repertoire of well-established techniques applicable to observational astronomy and physics. Classroom instruction is interspersed with hands-on analysis of astronomical data using the open-source R software package. The course is taught by a team of statistics and astronomy professors with opportunity for discussion of methodological issues. The program starts on Monday morning (June 7, 2010), and ends on Saturday June 12, 2010 at noon. The topics covered include:

* Exploratory data analysis
* Hypothesis testing and parameter estimation
* Regression
* Bootstrap resampling
* Model selection & goodness-of-fit
* Maximum likelihood methods & Bayes’ Theorem
* Non-parametric methods
* Monte Carlo methods
* Poisson processes
* Time series

The 2010 Summer School will be modeled on the last four Penn State Summer Schools and the two Indian Institute of Astrophysics-Penn State Summer School; see 2005, 2006, 2007, 2008 and 2009 lecture notes for the Penn State Summer Schools.

This is immediately followed by a supplementary program (June 12-14, 2010) on Statistics and Computation for Astronomical Surveys. This program starts on Saturday June 12 immediately following the main school and ends on Monday June 14 at noon. Statistical topics covered will include:

* Number count distributions (“logN-logS”) and the fundamental equation of stellar statistics
* Selection effects: truncation and censoring (Lynden-Bell, Kaplan-Meier product limit estimators)
* Classical survey biases (Eddington, Malmquist, Lutz-Kelker)
* Population modeling with hierarchical models
* Statistical cross-matching between surveys
* Introduction to Virtual Observatory software tools for querying and analyzing survey data

Participants may register for one or both programs. There is limited financial support for the program on astronomical surveys; requests for support should be sent to Tom Loredo (loredo, at astro.cornell.edu) by May 3.

Reduced and Processed Data http://hea-www.harvard.edu/AstroStat/slog/2008/reduced-data/ http://hea-www.harvard.edu/AstroStat/slog/2008/reduced-data/#comments Tue, 15 Jul 2008 03:55:09 +0000 vlk http://hea-www.harvard.edu/AstroStat/slog/?p=364 Hyunsook recently said that she wished that there were “some astronomical data depositories where no data reduction is required but one can apply various statistical analyses to the data in the depository to learn and compare statistical methods”. With the caveat that there really is no such thing (every dataset will require case specific reduction; standard processing and reduction are inadequate in all but the simplest of cases), here is a brief list:

  1. The 2 Megasecond Chandra observations of the Southern Deep Field, which have been processed, reduced, and mosaiced. (Coincidentally, just last week Peter Freeman had asked me for a nice dataset on which to try out spatial analysis algorithms, and for which some analysis already existed for people to check their results against. These were the data I recommended.)
  2. HEASARC’s W3Browse gives direct access to archived data from various missions. The data products have been already processed in some standard way.
  3. The Penn State Center for Astrostatistics maintains training datasets of various types
  4. ADC, as pointed out by Brian

There are many more, I am sure, and if people find any particularly good ones, please point them out in the comments!

AstroStatistics Summer School at PSU http://hea-www.harvard.edu/AstroStat/slog/2007/astrostat-summer-school-at-psu/ http://hea-www.harvard.edu/AstroStat/slog/2007/astrostat-summer-school-at-psu/#comments Mon, 29 Jan 2007 04:34:20 +0000 hlee http://hea-www.harvard.edu/AstroStat/slog/2007/astrostat-summer-school-at-psu/ Since Summer 2005, G. Jogesh Babu (Statistics) and Eric Feigelson (Astronomy) have organized lectures and lab sessions on statistics for astronomers and physicists. Lecturers are professors from Penn State statistics department and invited renown scientists from different countries. Students show diverse demography as well. Within a week or so, students listen Statistics 101 to recently published statistical theories particularly applied to astronomical data. They also learn how to use R, a statistical software and script language to perform statistics they learn through lectures. Past two years, this summer school proved its uniqueness and usefulness. More information on the upcoming school can be found at http://astrostatistics.psu.edu/su07/index.html and other topics regarding astrostatistics at Center for AstroStatistics at Penn State.
