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 کاملRetrieving Tree Heights in African Savanna Woodlands Using Three Stage
African savanna woodlands have an unpredictable spatial and temporal variability of woody biomass densities as a result of the interplay of rainfall, soil nutrients, fire, people and herbivores. These woodlands are characterised by heterogeneous species distribution with irregular vertical structures. A large percentage of rural communities in southern Africa rely on communal woodlands to meet ...
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.
