- factor(x, exclude = NULL) applied to a factor without NAs is a no-operation unless there are unused levels: in that case, a factor with the reduced level set is returned.

Pretest-Posttest Designs The Posttest Only Design With Non-Equivalent Control Groups. Pretest-posttest designs are an expansion of the posttest only design with nonequivalent groups, one of the simplest methods of testing the effectiveness of an intervention. In this design, which uses two groups, one group is given the treatment and the results are gathered at the end.

Introduction to Sets The empty set is a subset of every set. Let's define subset. A set is a subset of another set if every element of the set is also an element of the other set. Set A is a subset of Set B if every element of A is also an element of B.

Subgroup The equivalence of this definition with the earlier one is often called the subgroup condition. For full proof, refer: Sufficiency of subgroup condition. It has two forms (left and right): A subset of a group is termed a subgroup if it is nonempty and is closed under the left quotient of elements. In other words, a subset of a group is termed a subgroup if and only if is nonempty and whenever. A subset of a group is termed a subgroup if it is nonempty and is closed under the right quotient of elements.

Disjoint sets A pairwise disjoint family of sets. This definition of disjoint sets can be extended to any family of sets. A family of sets is pairwise disjoint or mutually disjoint if every two different sets in the family are disjoint. For example, the collection of sets { {1}, {2}, {3}, ... } is pairwise disjoint.

- Non-probability sampling is a type of sampling technique whereby all the units of a population do not have an equal chance of being selected in the sample. it may further be divided into. 1  Convenience: Sampling units are selected as per convenience of the researcher.

Binary tree A recursive definition using just set theory notions is that a (non-empty) binary tree is a triple (L, S, R), where L and R are binary trees or the empty set and S is a singleton set. Some authors allow the binary tree to be the empty set as well.

Point-Set Topology Topology > Point-Set Topology >. MathWorld Contributors > Budney >. The low-level language of topology, which is not really considered a separate branch of topology. Point-set topology, also called set-theoretic topology or general topology, is the study of the general abstract nature of continuity or closeness on spaces. Basic point-set topological notions are ones like continuity, dimension, compactness, and connectedness.

Union (set theory) In set theory, the union (denoted by ∪) of a collection of sets is the set of all elements in the collection. It is one of the fundamental operations through which sets can be combined and related to each other. For explanation of the symbols used in this article, refer to the table of mathematical symbols. 1 Union of two sets.

sum set - a group of things of the same kind that belong together and are so used; a set of books; a set of golf clubs; a set of teeth. direct sum - a union of two disjoint sets in which every element is the sum of an element from each of the disjoint sets.

- None is the pronoun form of no. None means ‘not one’ or ‘not any’. We use it as a pronoun to replace countable and uncountable nouns. We use it as subject or object: Slorne stared … and seemed to try to find some strength which would let her speak. But none came.

- Unsupervised classification is a method of identifying, grouping, and labeling features in an image according to their spectral values. In unsupervised classification, pixels are clustered together based on spectral homogeneity and spectral distance. An analyst may choose from a variety of techniques to measure distances.

:not () The negation CSS pseudo-class, :not(X), is a functional notation taking a simple selector X as an argument. It matches an element that is not represented by the argument. X must not contain another negation selector. Notes: Useless selectors can be written using this pseudo-class.

Budget Airline Football - A Fans Guide Select month... Bar none basically means without exception. The phrase is used to emphasize that a statement is completely true and often is used at the end of a phrase or sentence -- nearly always set off with a comma or commas. We have the best stadium, bar none, in college football. This is, bar none, the best ice cream I've ever had.

Why do natural numbers only consist of positive integers? Why are negative numbers not called natural? In set theory we define zero as the empty set, one as the set containing the empty set, two as the set containing both zero and one, and so on, as Natalia Nezvanova's answer points out. Some definitions start the natural numbers with 1, while others (which I'd say are more natural!) start with 0.

Recursively enumerable set The set S is the range of a partial recursive function. The set S is the range of a total recursive function or empty. If S is infinite, the function can be chosen to be injective. The set S is the range of a primitive recursive function or empty. Even if S is infinite, repetition of values may be necessary in this case.

- In mathematical sets, the null set, also called the empty set, is the set that does not contain anything. It is symbolized or { }. There is only one null set. This is because there is logically only one way that a set can contain nothing. The null set makes it possible to explicitly define the results of operations on certain sets that would otherwise not be explicitly definable.

NOTIFIABLE DISEASES Specificity refers to noncases not being reported as cases. Predictive value positive is the proportion of reported cases that truly are cases. A flexible system can adapt to changes in disease occurrence, or in changes in the reporting system, and still continue to function.

set The most basic relations in set theory can be summarized as follows. 1  A set S1 is a subset of set S if and only if every element of S1 is also an element of S. 2  A set S1 is a proper subset of set S if and only if every element of S1 is also an element of S, but there are some elements in S that are not elements of S1.
