Illustration of the Kolmogorov–Smirnov statistic. The red line is a model CDF, the blue line is an empirical CDF, and the black arrow is the KS statistic.. In statistics, the Kolmogorov–Smirnov test (K–S test or KS test) is a nonparametric test of the equality of continuous (or discontinuous, see Section 2.2), one-dimensional probability distributions that can be used to test whether a ...
Dead Frontier is a free-to-play, browser-based survival horror game which takes place in a post-apocalyptic, zombie-infested setting. It is operated by Creaky Corpse Ltd. [ 1 ] [ 2 ] Dead Frontier was released for open beta on April 21, 2008, [ 3 ] [ 4 ] and has over ten million registered accounts.
Mode (statistics) In statistics, the mode is the value that appears most often in a set of data values. [ 1] If X is a discrete random variable, the mode is the value x at which the probability mass function takes its maximum value (i.e., x=argmaxxi P (X = xi) ). In other words, it is the value that is most likely to be sampled.
Standard normal table. In statistics, a standard normal table, also called the unit normal table or Z table, [ 1] is a mathematical table for the values of Φ, the cumulative distribution function of the normal distribution. It is used to find the probability that a statistic is observed below, above, or between values on the standard normal ...
CompStat is a management system created in April 1994 by Bill Bratton and Jack Maple, whom Bratton met while he was chief of the New York City Transit Police and later hired as the New York Police Department 's top anti-crime specialist when he became Police Commissioner in 1993. [ 1] CompStat began as weekly meetings at One Police Plaza where ...
Qualitative analysis and reporting software includes chemometric functions for working with one or more text-format mass spectra. Mass-Up Open-source: Utility for proteomics designed to support the preprocessing and analysis of MALDI-TOF mass spectrometry data that loads data from mzML, mzXML and CSV files.
In descriptive statistics, the range of a set of data is size of the narrowest interval which contains all the data. It is calculated as the difference between the largest and smallest values (also known as the sample maximum and minimum ). [ 1] It is expressed in the same units as the data. The range provides an indication of statistical ...
Panel data. In statistics and econometrics, panel data and longitudinal data[ 1][ 2] are both multi-dimensional data involving measurements over time. Panel data is a subset of longitudinal data where observations are for the same subjects each time. Time series and cross-sectional data can be thought of as special cases of panel data that are ...
