genus

<p>Genus gives the abundance of 27 common tree genera in the tropical moist forest 
of the Congo-Basin and 40 geo-referenced environmental variables on one thousand 8 by 8 km plots
 (observations). Each plot's data was obtained by aggregating the data measured on a variable 
 number of previously sampled 0.5 ha sub-plots. Geo-referenced environmental variables were 
 used to describe the physical factors as well as vegetation characteristics. 
 14 physical factors were used pertaining the description of topography, geology and rainfall 
 of each plot. Vegetation is characterized through 16-days enhanced vegetation index (EVI) data.</p>


An extension of the Fisher Scoring Algorithm to combine PLS regression with GLM
estimation in the multivariate context. Covariates can also be grouped in themes.
