  2. Compact letter display - Wikipedia

    en.wikipedia.org/wiki/Compact_letter_display

    CLD facilitates the identification of variables, or factors, that have statistically different means (or averages) vs. the ones that do not have statistically different means (or averages). The basic technique of compact letter display is to label variables by one or more letters, so that variables are statistically indistinguishable if and ...

  3. Identifiability - Wikipedia

    en.wikipedia.org/wiki/Identifiability

    Usually the model is identifiable only under certain technical restrictions, in which case the set of these requirements is called the identification conditions. A model that fails to be identifiable is said to be non-identifiable or unidentifiable : two or more parametrizations are observationally equivalent .

  4. Identifier (computer languages) - Wikipedia

    en.wikipedia.org/wiki/Identifier_(computer...

    In Ruby a variable is automatically considered immutable if its identifier starts with a capital letter. In Go, the capitalization of the first letter of a variable's name determines its visibility (uppercase for public, lowercase for private). In some languages such as Go, identifiers uniqueness is based on their spelling and their visibility. [2]

    Scores on the TOEIC Listening and Reading test are determined by the number of correct answers. The number of correct responses on each section is multiplied by five and converted to a scaled score. Three TOEIC Listening and Reading scaled scores are given for each examinee: οne for the Listening Section; οne for the Reading Section

    These tests include the Graduate Record Examinations (GRE) (for graduate and professional school admissions), the Test of English as a Foreign Language (TOEFL) (for post-secondary admissions), the Test of English for International Communication (TOEIC) (for use by business and industry), and the Praxis Series (for teacher licensure and ...

  7. Parameter identification problem - Wikipedia

    en.wikipedia.org/wiki/Parameter_identification...

    An equation cannot be identified from the data if less than M − 1 variables are excluded from that equation. This is a particular form of the order condition for identification. (The general form of the order condition deals also with restrictions other than exclusions.) The order condition is necessary but not sufficient for identification.

  8. Variable and attribute (research) - Wikipedia

    en.wikipedia.org/wiki/Variable_and_attribute...

    The values are ordered in a logical way and must be defined for each variable. Domains can be bigger or smaller. The smallest possible domains have those variables that can only have two values, also called binary (or dichotomous) variables. Bigger domains have non-dichotomous variables and the ones with a higher level of measurement.

  9. Identifier - Wikipedia

    en.wikipedia.org/wiki/Identifier

    Registration plates are used to display identifiers for motor vehicles.. An identifier is a name that identifies (that is, labels the identity of) either a unique object or a unique class of objects, where the "object" or class may be an idea, person, physical countable object (or class thereof), or physical noncountable substance (or class thereof).
