Introduction 1 Introduction The GLM (General Linear Model) in SPSS has replaced manova1 as the point-and-click procedure for carrying out one-way, factorial, and repeated measures ANOVA and MANOVA analyses. It can also be used for regression analysis.
The general linear model or multivariate regression model is a statistical linear model.It may be written as = +, where Y is a matrix with series of multivariate measurements (each column being a set of measurements on one of the dependent variables), X is a matrix of observations on independent variables that might be a design matrix (each column being a set of observations on one of the.
where is the vector of responses, is the design matrix, is the vector of model parameters corresponding to the columns of , and is an vector of errors with
In PROC GLMPOWER, the model parameters are not specified directly, but rather indirectly as , which represents either conjectured response means or typical response values for each design profile. The values are manifested as the dependent variable in the MODEL statement. The vector is obtained from according to the least squares equation,
Note that, in general, there is not a 1-to-1 mapping between and . Many different scenarios for might lead to the same . If you specify with the intention of representing cell means, keep in mind that PROC GLMPOWER allows scenarios that are not valid cell means according to the model specified in the MODEL statement. For example, if exhibits an interaction effect but the corresponding interaction term is left out of the model, then the cell means () derived from differ from . In particular, the cell means thus derived are the projection of onto the model space. https://renewdogs362.weebly.com/blog/atv-repair-manual-download.
It is convenient in power analysis to parameterize the design matrix in three parts, , defined as follows:
It is useful to express the crossproduct matrix in terms of these three parts,
since this factors out the portion (N) depending on sample size and the portion () depending only on the design structure.

A general linear hypothesis for the univariate model has the form
where is an contrast matrix (assumed to be full rank) and is the null value (usually just a vector of zeros). Note that effect tests are just contrasts that use special forms of . Thus, this scheme covers both effect tests and custom contrasts.
The test statistic is
