10.1111/j.1365-2966.2010.17904.x We present the galaxy stellar mass function and its evolution in clusters from z similar to 0.8 to the current epoch, based on the WIde-field Nearby Galaxy-cluster ...

What Is A Probability Density Function? A probability density function, also known as a bell curve, is a fundamental statistics concept, that describes the likelihood of a continuous random variable ...

Abstract: Estimating the probability mass function (PMF) of a set of discrete random variables using a low-rank model for the PMF tensor has recently gained much attention. However, detecting the rank ...

Add a description, image, and links to the initial-mass-function topic page so that developers can more easily learn about it.

The COS method was introduced in Fang & Oosterlee (2008) and then was applied to pricing a variety of stock options for continuous random variables. This paper adapts the Fourier-cosine series (COS) ...

New research reveals that the mass of newly born stars (yellow, orange, and red circles stand for stars from higher to lower mass) varies with their metal abundances and their birth time (inner circle ...

The Frèchet distribution has aided the modelling of scientific data in many contexts. We demonstrate how it can be adapted to model astrophysical data. We analyze the truncated version of the Frèchet ...
