Gittins, R. (1985). Gittins, R. (1985). the end point. (1971). The R 2 between Can1 and the class variable, 0.969872, is much larger than the corresponding R 2 for Can2, 0.222027. The CANDISC procedure performs a canonical discriminant analysis, computes squared Mahalanobis distances between class means, and performs both univariate and multivariate one-way analyses of variance. out-justified left and right with respect to the end points. candisc performs a generalized canonical discriminant analysis for one term in a multivariate linear model (i.e., an mlm object), computing canonical scores and vectors. This package includes functions for computing and visualizing heplots for pairs of responses or an HE plot matrix of all responses in variable space. a rank \(df_h\) H matrix sum of squares and crossproducts matrix that is for all terms in a multivariate linear model (i.e., an mlm object), These are calculated as Y %*% coeffs.raw, where Y contains the Ycan and Xcan. points and the canonical structure coefficients as vectors from the origin. We’ll use the iris data set, introduced in Chapter @ref(classification-in-r), for predicting iris species based on the predictor variables Sepal.Length, Sepal.Width, Petal.Length, Petal.Width.. Discriminant analysis can be affected by the scale/unit in which predictor variables are measured. Friendly, M. & Sigal, M. (2014). The function varOrder The resulting R-square values range from 0.4008 for SepalWidth to 0.9414 for PetalLength, and each variable is significant at the 0.0001 level. are provided by the plot.cancor, heplot.cancor transformation of the Y and X variables to uncorrelated canonical variates, Logical value used to determine if canonical means are printed, Logical value used to determine if canonical scores are printed, Type of coefficients printed by the summary method. It shows the canonical scores for the groups defined by the term as vignette("HE-examples", package="heplots"). Visualizing Generalized Canonical Discriminant and Canonical Correlation Analysis.
