آمار برای ستاره شناسی:‌روش‌های آماری برای تجزیه و تحلیل داده‌های ستاره شناسی

چکیده مقاله

The data analyzed here are the simulated numbers of galaxies in cubic cells in the universe, which has been provided to the author by a famous astronomer from an astronomical observatory center in Spain. The observed cubic window was divided into 1000 (sample galaxy10), 8000 (sample galaxy20) and 27000 (sample galaxy30) cubic sub windows and the numbers of galaxies in these sub-windows were counted. An interesting traditional question is finding the distribution of the number of galaxies in these sub windows. Here the discrete Weibull, the negative binomial distribution has been fitted to these data. Afterward, the expected number of galaxies has been derived to quantify the implied model error.
