mfa 157
mfa
Multiple Factorial Analysis
Description
Usage
performs a multiple factorial analysis, using an object of class ktab.
mfa(X, option = c("lambda1", "inertia", "uniform", "internal"),
scannf = TRUE, nf = 3)
## S3 method for class 'mfa':
plot(x, xax = 1, yax = 2, option.plot = 1:4, ...)
## S3 method for class 'mfa':
print(x, ...)
## S3 method for class 'mfa':
summary(object, ...)
Arguments
X
K-tables, an object of class ktab
option a string of characters for the weighting of arrays options :
lambda1
inertia
uniform
internal
scannf
nf
Value
weighting of group k by the inverse of the first eigenvalue of the k analysis
weighting of group k by the inverse of the total inertia of the array k
uniform weighting of groups
weighting included in X$tabw
a logical value indicating whether the eigenvalues bar plot should be displayed
if scannf FALSE, an integer indicating the number of kept axes
x, object an object of class ’mfa’
xax, yax
option.plot
the numbers of the x-axis and the y-axis
an integer between 1 and 4, otherwise the 4 components of the plot are displayed
... further arguments passed to or from other methods
Returns a list including :
tab
rank
eig
li
TL
a data frame with the modified array
a vector of ranks for the analyses
a numeric vector with the all eigenvalues
a data frame with the coordinates of rows
a data frame with the factors associated to the rows (indicators of table)
