We derive methods for applying the V/V/sub max/ variable when several complete samples are analyzed simultaneously. A new, related, variable, V/sub e//V/sub a/, which is superior to V/V/sub max/ when sufficient observational data are available, is introduced. We show how statistically independent complete samples can be generated from partially overlapping samples such that each observed object appears only once in the analysis. These methods make it possible to combine the information from… 
Both density- and luminosity-evolution of quasars proceed sumultaneously. If only one of them is considered, the value of 〈V/Vmax〉 would be too high. Here we present an idea that the quasar
On the Cosmological Evolution of BL Lacertae Objects
We study the cosmological evolution of BL Lac objects by applying the Ve/Va analysis to a new sample of 55 objects, presented for the first time in this paper. This sample has been selected from the
New Statistical Methods for Analysis of Large Surveys: Distributions and Correlations
The aim of this paper is to describe new statistical methods for determination of the correlations among and distributions of physical parameters from a multivariate data with general and arbitrary
Does the Number Density of Elliptical Galaxies Change at z < 1?
We have performed a detailed V/Vmax test for a sample of the Canada-France Redshift Survey (CFRS) for the purpose of examining whether the comoving number density of field galaxies changes
A Generalization of the V/Vmax Test
This analysis shows that the values of n/nmax are uniformly distributed in the interval [0, 1] and the expectation value of ⟨n/n max⟩ is ½ in any kind of distribution of the objects if the luminosity function adopted is correct.
Star Formation in Herschel's Monsters versus Semi-Analytic Models
We present a direct comparison between the observed star formation rate functions (SFRF) and the state-of-the-art predictions of semi-analytic models (SAM) of galaxy formation and evolution. We use
The 2.4 $\mu$m Galaxy Luminosity Function as Measured Using WISE. I. Measurement Techniques
The astronomy community has at its disposal a large back catalog of public spectroscopic galaxy redshift surveys that can be used for the measurement of luminosity functions (LFs). Utilizing the back
A new technique to efficiently select Compton-thick AGN
We present a new efficient diagnostic method, based on mid-infrared and X-ray data, to select local (z -0.2. We build up a sample of 43 CT AGN candidates using data from IRAS-PSC and 2XMM catalogue.
The X-Ray Luminosity Function of Nearby Rich and Poor Clusters of Galaxies:A Cosmological Probe
In this Letter, we present a new determination of the local (z≤0.09) X-ray luminosity function (XLF) using a large, statistical sample of 294 Abell clusters and the ROSAT All-Sky Survey. Despite the
Selection Functions in Astronomical Data Modeling, with the Space Density of White Dwarfs as a Worked Example
Statistical studies of cataloged object properties are central to astrophysics. But one cannot model those objects’ population properties without the sample’s selection function, the quantitative
