Lists model equations, the summary as returned by summary.modFit,
the chi2 error levels calculated according to FOCUS guidance (2006) as far
as defined therein, and optionally the data, consisting of observed, predicted
and residual values.
Usage
## S3 method for class 'mkinfit'
summary(object, data = TRUE, distimes = TRUE, alpha = 0.05, ...)
## S3 method for class 'summary.mkinfit'
print(x, digits = max(3, getOption("digits") - 3), ...)
Arguments
object
an object of class mkinfit.
x
an object of class summary.mkinfit.
data
logical, indicating whether the data should be included in the summary.
distimes
logical, indicating whether DT50 and DT90 values should be included.
alpha
error level for confidence interval estimation from t distribution
digits
Number of digits to use for printing
...
optional arguments passed to methods like print.
Value
The summary function returns a list derived from
summary.modFit, with components, among others
version, Rversion
The mkin and R versions used
date.fit, date.summary
The dates where the fit and the summary were produced
use_of_ff
Was maximum or minimum use made of formation fractions
cov.unscaled, cov.scaled, info, niter, stopmess, par
As in summary.modFit
bpar
Optimised and backtransformed parameters
diffs
The differential equations used in the model
data
The data (see Description above).
start
The starting values and bounds, if applicable, for optimised parameters.
fixed
The values of fixed parameters.
errmin
The chi2 error levels for each observed variable.
bparms.ode
All backtransformed ODE parameters, for use as starting parameters for
related models.
ff
The estimated formation fractions derived from the fitted model.
distimes
The DT50 and DT90 values for each observed variable.
SFORB
If applicable, eigenvalues of SFORB components of the model.
The print method is called for its side effect, i.e. printing the summary.
