Package 'trama.multi'
| Title: |
Multivariate Analysis Collection for trama |
| Description: |
Nodes for multivariate analysis in a trama graph:
principal component analysis with scree, biplot and correlation
circle; factor analysis by maximum likelihood or principal
axis, with orthogonal (varimax, quartimax, equamax) and oblique
(promax, oblimin) rotations; linear and quadratic discriminant
analysis with exact leave-one-out predictions; logistic
regression (binary and multinomial) as a classifier; jackknife
bias, standard errors and pseudovalues for component, factor,
discriminant and logistic statistics; and the diagnostics that
come first (KMO, Bartlett's sphericity, Horn's parallel
analysis, Box's M); distance matrices (Euclidean, Mahalanobis
D2, Gower), hierarchical clustering with cophenetic
correlation, k-means and Tocher's optimization method; and
one-way MANOVA with optional blocks. Ships example data with
known structure. Builds on trama.data for tables, trama.view
for plots and trama.models, whose model contract the
classifiers implement (prediction, confusion and ROC are its
nodes). |
