mkin (version 0.9-31)

summary.mkinfit: Summary method for class "mkinfit".

Description

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
• residuals, residualVariance, sigma, modVariance, df
  As in summary.modFit
• 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.
