This simple law, despite my trial of full text search, was not showing in ADS. As discussed in systematic errors, astronomers, like physicists, show their error components in two additive terms; statistical error + systematic error. To explain such decomposition and to make error analysis statistically rigorous, the **law of total variance (LTV)** seems indispensable. Continue reading ‘[MADS] Law of Total Variance’ »

To be exact, the title of this posting should contain *5th week, Oct*, which seems to be the week of EGRET. In addition to astro-ph papers, although they are not directly related to astrostatistics, I include a few statistics papers which may be profitable for astronomical data analysis.
