Tied ranks
| Statistic terms |
In a nonparametric test involving ranked data, if two data have tied values then they will deserve to receive the same rank value. it is generally agreed that this should be the average of the ranks which would have been assigned if the values had been di

Rank swapping provides a way of using continuous variables to define pairs of records for swapping. instead of insisting that variables match (agree exactly), they are defined to be close based on their proximity to each other on a list sorted on the cont

Rankboost, английский
Rankboost is an extension of the basic adaboost methodology that has been modified to handle training data that contains partial orderings. an example would be movie or book ratings where each respondent orders (ranks) a small subset of the available movies/books. the rankboost algorithm derives a combined ordering that attempts to preserve the original orderings.
Ranke, английский
Nonparametric, английский
A procedure is nonparametric if it does not rely upon "simple" parametric forms in the data, such as a gaussian, poisson, or binomial distributions. typically, a nonparametric distribution relies upon the data to form the distribution, and derives its properties from the way the data was sampled (selected) and the way in which it is manipulated (e.g., randomization tests, classification trees). this makes the procedure more robust, but less efficient when a parametric distribution is reasonable. for example, a tree-based classifier can outperform a logistic regression when the data are not linear, but will be less effective when the data do meet the linearity assumptions of a logistic regression. note that nonparametric procedures essentially treat the data as the distribution, so that the base distribution involved is the observed data distribution, which is a form of a tabular distribution. these procedures are sometimes called "distribution free," again meaning "doesn`t use a simple parametric form," rather than "doesn`t have any distribution." see also: parametric distribution. non-terminal symbol a symbol in a grammar that can be rewritten into further symbols when processing a statement. see also: production, terminal symbol. non-von a family of massively parallel computer architectures developed at columbia university in the mid-1980s. the systems are characterized by a special form of "active memory", consisting of many elements each with a small amount of local memory, a specialized cpu, and i/o switches that permit the machine to be dynamically reconfigured.

Null hypothesis, английский
- In order to test whether a supposed interesting pattern exists in a set of data, it is usual to propose a null hypothesis that the pattern does not exist. it is the unexpectedness of the degree of departure of the observed data, relative to the pattern ex
- In hypothesis testing, the hypothesis we wish to falsify on the basis of the data. the null hypothesis is typically that something is not present, that there is no effect, or that there is no difference between treatment and control.
- A hypothesis of the form: there is no difference between a and b. this form of the hypothesis is the basis for statistical tests of significance, such as the t-test and the f-test. in the t-test, a and b are mean values. in the f-test, a and b are variances (squares of standard deviations)
- Нулевая гипотеза
- Основная гипотеза. см. hypothesis testing (проверка гипотезы).
