monomvn.s3 {monomvn} | R Documentation |
Summarizing, printing, and plotting the contents of a
"monomvn"
-class object
## S3 method for class 'monomvn': summary(object, Si = FALSE, ...) ## S3 method for class 'summary.monomvn': print(x, ...) ## S3 method for class 'summary.monomvn': plot(x, gt0 = FALSE, main = NULL, xlab = "number of zeros", ...)
object |
a "monomvn" -class object that must be named
object for the generic methods summary.monomvn |
x |
a "monomvn" -class object that must be named x
for generic printing and plotting via
print.summary.monomvn and
plot.summary.monomvn |
Si |
boolean indicating whether object$S should be
inverted and inspected for zeros within
summary.monomvn , indicating pairwise independence;
default is FALSE |
gt0 |
boolean indicating whether the histograms in
plot.summary.monomvn should exclude columns
of object$S or Si without any zero entries |
main |
optional text to be added to the main title of the histograms
produced by the generic plot.summary.monomvn |
xlab |
label for the x-axes of the histograms produced by
plot.summary.monomvn ; otherwise default
automatically-generated text is used |
... |
passed to print.monomvn , or
plot.default |
These functions work on the output from both monomvn
and bmonomvn
.
print.monomvn
prints the call
followed by a
summary of the regression method used at each iteration of the
algorithm. It also indicates how many completely observed features
(columns) there were in the data.
For non-least-squares regressions (i.e., plsr, lars
and lm.ridge
methods)
and indication of the method used for selecting the
number of components (i.e., CV
, LOO
, etc., or
none
) is provided
summary.monomvn
summarizes information about the
number of zeros in the estimated covariance matrix object$S
and its inverse
print.summary.monomvn
calls print.monomvn
on the object
and then prints the result of
summary.monomvn
plot.summary.monomvn
makes histograms of the number of
zeros in the columns of object$S
and its inverse
summary.monomvn
returns a
"summary.monomvn"
-class object, which is a list
containing (a subset of) the items below. The other
functions do not return values.
obj |
the "monomvn" -class object |
S0 |
a vector containing the number of zeros in each column
of object$S |
cond |
if input Si = TRUE this field contains the
proportion of zeros in the inverse of object$S |
Si0 |
if input Si = TRUE this field contains a
vector with the number of zeros in each column of the inverse
of object$S |
There is one further S3 function for "monomvn"
-class
objects that has its own help file: plot.monomvn
