The idea behind Chauvenet's criterion finds a probability band that reasonably contains all n samples of a data set, centred on the mean of a normal distribution.By doing this, any data point from the n samples that lies outside this probability band can be considered an outlier, removed from the data set, and a new mean and standard deviation based on the remaining values and new sample size ...
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.
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 ...
In statistics, Duncan's new multiple range test ( MRT) is a multiple comparison procedure developed by David B. Duncan in 1955. Duncan's MRT belongs to the general class of multiple comparison procedures that use the studentized range statistic qr to compare sets of means. David B. Duncan developed this test as a modification of the Student ...
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 ...
Kuiper's test. Kuiper's test is used in statistics to test that whether a data sample come from a given distribution (one-sample Kuiper test), or whether two data samples came from the same unknown distribution (two-sample Kuiper test). It is named after Dutch mathematician Nicolaas Kuiper.
In statistics, the k th order statistic of a statistical sample is equal to its k th-smallest value. [ 1 ] Together with rank statistics, order statistics are among the most fundamental tools in non-parametric statistics and inference . Important special cases of the order statistics are the minimum and maximum value of a sample, and (with some ...
In statistics and in particular in regression analysis, leverage is a measure of how far away the independent variable values of an observation are from those of the other observations. High-leverage points, if any, are outliers with respect to the independent variables. That is, high-leverage points have no neighboring points in space, where ...
