The AstroStat Slog » misnomer http://hea-www.harvard.edu/AstroStat/slog Weaving together Astronomy+Statistics+Computer Science+Engineering+Intrumentation, far beyond the growing borders Fri, 09 Sep 2011 17:05:33 +0000 en-US hourly 1 http://wordpress.org/?v=3.4 [ArXiv] 1st week, Apr. 2008 http://hea-www.harvard.edu/AstroStat/slog/2008/arxiv-1st-week-apr-2008/ http://hea-www.harvard.edu/AstroStat/slog/2008/arxiv-1st-week-apr-2008/#comments Sun, 06 Apr 2008 15:10:15 +0000 hlee http://hea-www.harvard.edu/AstroStat/slog/?p=263 I’m very curious how astronomers began to use Monte Carlo Markov Chain instead of Markov chain Monte Carlo. The more it becomes popular, the more frequently Monte Carlo Markov Chain appears. Anyway, this week, I added non astrostatistical papers in the list: a tutorial, big bang, and biblical theology.

  • [astro-ph:0803.4089] R. Trotta
    Bayes in the sky: Bayesian inference and model selection in cosmology (Bayesian cosmology tutorial).

paper with a very interesting title: [astro-ph:0803.3604]
Was There A Big Bang? by R. K. Soberman and M. Dubin

not astrostatistics but atypical statistical application, interesting topic, and good discussions:[stat.AP:0804.0079]
Statistical analysis of an archeological find by A. Feuerverger
Discussants are S.M. Stigler, C. Fuchs, D.L. Bentley, S.M. Bird, H. Höfling, L. Wasserman, R. Ingermanson, J. Mortera, P. Vicard, J.B. Kadane (Click names).

By the way, there is a paper about solar cycle, PCA, ICA, and Lomb-Scargle periodogram.

  • [astro-ph:0803.3154]B. G. Elmegreen
    The Stellar Initial Mass Function in 2007: A Year for Discovering Variations

  • [astro-ph:0803.3260]J.K. Lawrence, A.C. Cadavid & A. Ruzmaikin
    Rotational quasi periodicities and the Sun – heliosphere connection (I wish arxiv provides keywords. My keywords to this preprint are solar cycle, Lomb-Scargle periodogram, PCA, ICA, all interesting to CHASC folks. Particularly, I felt some similarity to one of stat310 talks about Gravity Probe B)

  • [astro-ph:0803.3775] L. Samushia, & B. Ratra
    Constraints on Dark Energy from Galaxy Cluster Gas Mass Fraction versus Redshift data (another example of Monte Carlo Markov Chain, not Markov chain Monte Carlo in the abstract but MCMC is not their research focus)

A book titled MCMC in astronomy will be a best seller. There are, in addition, very interesting non MCMC preprints.

  • [astro-ph:0803.2130] R. Aurich
       A spatial correlation analysis for a toroidal universe (MCMC)

  • [astro-ph:0803.2120]M. Martinez & M. Errando
       A new method to study energy-dependent arrival delays on photons from astrophysical sources (Likelihood function and goodness-of-fit)

  • [astro-ph:0803.2234] G. Dobler et.al.
       Lensing Probabilities for Spectroscopically Selected Galaxy-Galaxy Strong Lenses (could it be helpful to lay out GREAT08 challenges statistically?)

  • [astro-ph:0803.2529] M. Bazot, S. Bourguignon and J. Christensen-Dalsgaard
       Estimation of stellar parameters using Monte Carlo Markov Chains (MCMC)

  • [stat.AP:0803.2623] F. Dup\’e, J. Fadili, and J. L. Starck
       A proximal iteration for deconvolving Poisson noisy images using sparse representations

I’m used to see Markov Chain Monte Carlo (or lower case c in Chain) from statistical journals but in astronomical journals, Monte Carlo Markov Chains seem to be standard.
