Class TwoWayAnovaTable summarizes the information of a traditional two-way Analysis of Variance (ANOVA) table.

Class for performing a Type I ANOVA on unbalanced data. See the description of the base class TwoWayAnovaUnbalanced for a description of the notation. Type I, also called "sequential" sum of squares: SS(A) for factor A. SS(B | A) for factor B. SS(AB | B, A) for interaction AB. This tests the main effect of factor A, followed by the main effect of factor B after the main effect of A, followed by the interaction effect AB after the main effects.

Class for performing a Type II ANOVA on unbalanced data. See the description of the base class TwoWayAnovaUnbalanced for a description of the notation. SS(A | B) for factor A. SS(B | A) for factor B. SS(AB | A, B) for interaction. This type tests for each main effect after the other main effect. Note that no significant interaction is assumed and you should look look at the test for interaction first (SS(AB | A, B)) and only if interaction after the main effects AB is not significant continue with the analysis for main effects.

Class for performing a Type III ANOVA on unbalanced data. See the description of the base class TwoWayAnovaUnbalanced for a description of the notation. SS(A | B, AB) for factor A. SS(B | A, AB) for factor B. SS(AB | A, B) for interaction. This type tests for the presence of a main effect after the other main effect and interaction. This approach is therefore valid in the presence of significant interactions. However, it is often not interesting to interpret a main effect if interactions are present (generally speaking, if a significant interaction is present, the main effects should not be further analysed).

Class TwoWayAnovaUnbalanced is the base class for performing a two way ANOVA when the number of observations in each cell is not the same (an unbalanced design). In this case the main and interaction effects are interdependent, and we must obtain the marginal sum of squares associated with each factor after all the other factors have already been included in the model (the marginal sum of squares for each variable equals the incremental sum of squares for that variable when it is entered into the equation last). In terms of a regression approach to ANOVA, the marginal sum of squares due to a factor is the sum of squares for the set of dummy variables associated with that factor when those dummy variables are entered into the model last, after all other dummy variables. Classes deriving from TwoWayAnovaUnbalanced provide the ordering of dummy regression variables and use the base class to compute the resulting regressions and sums of squares.

Class containing the linear regression object computed from a particular ordering of factor and interaction parameters. Note that a factor parameter or interaction parameters may be absent depending on which type of sum of squares is being computed.

As long as the dummy regression parameters are the same, we may use the same regression matrix to compute the various marginal sums of squares. Since the dummy variables for a given factor, or the interaction parameters, will always be contiguous columns in the regression matrix, their location can be specified with slices. The ParameterSlices class specifies the slices where factor A, factor B, and interaction dummy variables are located in the regression matrix. The following terminology is used throughout: Regression matrix - the matrix of regression parameters include the intercept parameter, which is expressed as a leading column of 1's in the matrix. Predictor matrix - The matrix of regression parameters excluding the intercept parameter. Thus regression parameters start at column 1 in the regression matrix and column 0 in the predictor matrix.

Enumeration for specifying the type of transformation of a normal random variate in the Johnson system.

An enumeration representing methods used to choose the initial cluster centers.

Options for handling the boundaries in a moving window filter.

Output functions are functions supplied by the user to derived ODE solvers. These functions are called by solver during 1. Initialization. Before the first integration step is performed. 2. After each integration step. 3. When the solver is complete. Output functions are called with an OutputFunctionFlag parameter indicating under which of the above conditions it is being invoked.
