discrimin
Linear Discriminant Analysis (descriptive statistic)
Description
Usage
performs a linear discriminant analysis.
discrimin(dudi, fac, scannf = TRUE, nf = 2)
## S3 method for class 'discrimin':
plot(x, xax = 1, yax = 2, ...)
## S3 method for class 'discrimin':
print(x, ...)
Arguments
dudi
fac
scannf
nf
x
Value
xax
yax
a duality diagram, object of class dudi
a factor defining the classes of discriminant analysis
a logical value indicating whether the eigenvalues bar plot should be displayed
if scannf FALSE, an integer indicating the number of kept axes
an object of class ’discrimin’
the column number of the x-axis
the column number of the y-axis
... further arguments passed to or from other methods
returns a list of class ’discrimin’ containing :
nf
eig
fa
li
va
cp
gc
a numeric value indicating the number of kept axes
a numeric vector with all the eigenvalues
a matrix with the loadings: the canonical weights
a data frame which gives the canonical scores
a matrix which gives the cosines between the variables and the canonical scores
a matrix which gives the cosines between the components and the canonical
scores
a data frame which gives the class scores
