summary.rsm {marg} | R Documentation |
Returns a summary list for a fitted regression-scale model.
## S3 method for class 'rsm': summary(object, correlation = FALSE, digits = NULL, ...)
object |
a fitted rsm object. This is assumed to be the result of
some fit that produces an object inheriting from the class
rsm , in the sense that the components returned by the
rsm function will be available.
|
correlation |
logical argument. If TRUE , the correlation matrix for the
coefficients is computed; default is TRUE .
|
digits |
a non-null value specifies the minimum number of significant
digits to be printed in values. If NULL , the value of
digits set by options is used.
|
... |
absorbs any additional argument. |
This function is a method for the generic function
summary()
for class rsm
. It can be invoked by
calling summary
for an object of the appropriate class, or
directly by calling summary.rsm
regardless of the class of
the object.
A list is returned with the following components:
coefficients |
a matrix with four columns, containing the coefficients, their standard errors, the z-values (or Wald statistics) and the associated p-values based on the standard normal approximation to the distribution of the z statistic. |
dispersion |
the value of the scale parameter used in the computations. |
fixed |
a logical value. If TRUE , the scale parameter is known.
|
residuals |
the response residuals. |
cov.unscaled |
the unscaled covariance matrix, i.e, a matrix such that multiplying it by the squared scale parameter, or an estimate thereof, produces an estimated (asymptotic) covariance matrix for the coefficients. |
correlation |
the computed correlation matrix for the coefficients in the model. |
family |
the entire family.rsm object used.
|
loglik |
the computed log likelihood. |
terms |
an object of mode expression and class term
summarizing the formula.
|
df |
the number of degrees of freedom for the model and for the residuals. |
iter |
the number of IRLS iterations used to compute the estimates. |
nas |
a logical vector indicating which, if any, coefficients are missing. |
call |
an image of the call that produced the rsm object, but
with the arguments all named and with the actual formula.
|
digits |
the value of the digits argument.
