Hartley's test is related to Cochran's C test [6] [7] in which the test statistic is the ratio of max(s j 2) to the sum of all the group variances.Other tests related to these, have test statistics in which the within-group variances are replaced by the within-group range.
Analysis of covariance ( ANCOVA) is a general linear model that blends ANOVA and regression. ANCOVA evaluates whether the means of a dependent variable (DV) are equal across levels of one or more categorical independent variables (IV) and across one or more continuous variables. For example, the categorical variable (s) might describe treatment ...
Robert David Keppel (June 15, 1944 – June 14, 2021) was an American law enforcement officer and detective. He was also an associate professor at the University of New Haven and Sam Houston State University. Keppel was known for his contributions to the investigations of Ted Bundy and Gary Ridgway, and also assisted in the creation of HITS ...
Fuzzy logic is an attempt to apply the easy design of logic controllers to the control of complex continuously varying systems. Basically, a measurement in a fuzzy logic system can be partly true. The rules of the system are written in natural language and translated into fuzzy logic.
Contemporary architecture is the architecture of the 21st century. No single style is dominant. [ 1] Contemporary architects work in several different styles, from postmodernism, high-tech architecture and new references and interpretations of traditional architecture [ 2][ 3] to highly conceptual forms and designs, resembling sculpture on an ...
The design of experiments ( DOE or DOX ), also known as experiment design or experimental design, is the design of any task that aims to describe and explain the variation of information under conditions that are hypothesized to reflect the variation. The term is generally associated with experiments in which the design introduces conditions ...
Optimal designs reduce the costs of experimentation by allowing statistical models to be estimated with fewer experimental runs. Optimal designs can accommodate multiple types of factors, such as process, mixture, and discrete factors. Designs can be optimized when the design-space is constrained, for example, when the mathematical process ...
