Summary method for class "mkinfit"
Description
Lists model equations, initial parameter values, optimised parameters with some uncertainty statistics, the chi2 error levels calculated according to FOCUS guidance (2006) as defined therein, formation fractions, DT50 values 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. |
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 |
... |
optional arguments passed to methods like |
x |
an object of class |
digits |
Number of digits to use for printing |
Value
The summary function returns a list 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 |
diffs |
The differential equations used in the model |
use_of_ff |
Was maximum or minimum use made of formation fractions |
bpar |
Optimised and backtransformed parameters |
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. |
errparms |
Error model parameters. |
ff |
The estimated formation fractions derived from the fitted model. |
distimes |
The DT50 and DT90 values for each observed variable. |
SFORB |
If applicable, eigenvalues and fractional eigenvector component g of SFORB systems in the model. |
The print method is called for its side effect, i.e. printing the summary.
