Benthic Macroinvertabrate distribution in Tajan River Using Canonical Correspondence Analysis
The distribution of macroinvertebrate communities from 5 sampling sites of the Tajan River were used to examine the relationship among physiochemical parameters with macroinvertebrate communities and also to assess ecological classification system as a tool for the management and conservation purposes. The amount of variation explained in macroinvertebrate taxa composition is within values r...
متن کاملSimple and Canonical Correspondence Analysis Using the R Package anacor
This paper presents the R package anacor for the computation of simple and canonical correspondence analysis with missing values. The canonical correspondence analysis is specified in a rather general way by imposing covariates on the rows and/or the columns of the two-dimensional frequency table. The package allows for scaling methods such as standard, Benzécri, centroid, and Goodman scaling. ...

متن کاملVariants of Simple Correspondence Analysis
This paper presents the R package CAvariants (Lombardo and Beh, 2017). The package performs six variants of correspondence analysis on a two-way contingency table. The main function that shares the same name as the package – CAvariants – allows the user to choose (via a series of input parameters) from six different correspondence analysis procedures. These include the classical approach to (sy...
متن کاملCanonical Pseudo-Correspondence
Generalizing an example from (Fine 1975) and inspired by a theorem in (Jónsson 1994), we prove that any modal formula of the form π(p ∨ q) ↔ π(p) ∨ π(q) (with π(p) a positive formula) is canonical. We also prove that any such formula is strongly sound and complete with respect to an elementary class of frames, definable by a first order formula which can be read off from π.
