Scale parameter¶
In probability theory and statistics, a scale parameter is a special kind of numerical parameter of a parametric family of probability distributions.
Core Idea¶
Scale parameter is treated here as the recurring computerscienceandinformation identity summarized by this source-grounded definition: In probability theory and statistics, a scale parameter is a special kind of numerical parameter of a parametric family of probability distributions. In probability theory and statistics, a scale parameter is a special kind of numerical parameter of a parametric family of probability distributions. The larger the scale parameter, the more spread out the distribution. This scale factor is defined as the theoretical value of the value obtained by dividing the required scale parameter by the asymptotic value of the.
Scope of Application¶
-
Definition. If a family of probability distributions is such that there is a parameter s (and other parameters θ) for which the cumulative distribution function satisfies.
-
Definition. If the probability density exists for all values of the complete parameter set, then the density (as a function of the scale parameter only) satisfies.
-
Families with Location Parameters. In the case where a parametrized family has a location parameter, a slightly different definition is often used as follows.
-
Examples. In practice the normal distribution is often parameterized in terms of the squared scale \sigma^2 , which corresponds to the variance of the distribution.
-
Estimation. A statistic can be used to estimate a scale parameter so long as it.
Clarity¶
A clear use of Scale parameter names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is In probability theory and statistics, a scale parameter is a special kind of numerical parameter of a parametric family of probability distributions.
Manages Complexity¶
Scale parameter compresses multiple computerscienceandinformation details into a stable diagnostic relation. The source shows both the central mechanism—in order to make the statistic a consistent estimator for the scale parameter, one must in general multiply the statistic by a constant scale factor.—and the practical consequence—note that the scale factor depends on the distribution in question.
Abstract Reasoning¶
- Type the carrier. Identify the computerscienceandinformation entities to which the claim applies.
- State the relation. Use the source-grounded identity: In probability theory and statistics, a scale parameter is a special kind of numerical parameter of a parametric family of probability distributions.
- Check operation and conditions. This scale factor is defined as the theoretical value of the value obtained by dividing the required scale parameter by the asymptotic value of the statistic.
- Demand recognition evidence.
Knowledge Transfer¶
Within the home domain. Knowledge about Scale parameter transfers literally when a new case preserves the same carrier type, relation, and recognition test. If a family of probability distributions is such that there is a parameter s (and other parameters θ) for which the cumulative distribution function satisfies. If the probability density exists for all values of the complete parameter set, then the density (as a function of the scale parameter only) satisfies. Beyond the home domain. No canonical parent is asserted for Scale parameter.
Neighborhood in Abstraction Space¶
Scale parameter sits in a crowded region of the domain-specific corpus (38th percentile for distinctiveness): several abstractions share nearly its structure, so a description that fits it tends to fit its neighbors too.
