summary
method for class "nls"
.
"summary"(object, correlation = FALSE, symbolic.cor = FALSE, ...)
"print"(x, digits = max(3, getOption("digits") - 3), symbolic.cor = x$symbolic.cor, signif.stars = getOption("show.signif.stars"), ...)
"nls"
."summary.nls"
, usually the result of a
call to summary.nls
.TRUE
, the correlation matrix of
the estimated parameters is returned and printed.TRUE
, print the correlations in
a symbolic form (see symnum
) rather than as numbers.TRUE
, significance stars
are printed for each coefficient.summary.nls
computes and returns a list of summary
statistics of the fitted model given in object
, using
the component "formula"
from its argument, plus
nls
.cov.unscaled
, if correlation = TRUE
is specified and
there are a non-zero number of residual degrees of freedom.correlation
is true.) The value
of the argument symbolic.cor
. print.summary.nls
tries to be smart about formatting the
coefficients, standard errors, etc. and additionally gives
significance stars if signif.stars
is TRUE
.
Correlations are printed to two decimal places (or symbolically): to
see the actual correlations print summary(object)$correlation
directly.
nls
, summary
. Function coef
will extract the matrix of coefficients
with standard errors, t-statistics and p-values.
