intervals.saem.mmkin

Confidence intervals for parameters in saem.mmkin objects

Calculation routines based on the FOCUS Kinetics Report (2006,
2014). Includes a function for conveniently defining differential equation
models, model solution based on eigenvalues if possible or using numerical
solvers. If a C compiler (on windows: 'Rtools') is installed, differential
equation models are solved using automatically generated C functions.
Heteroscedasticity can be taken into account using variance by variable or
two-component error models as described by Ranke and Meinecke (2018)
<doi:10.3390/environments6120124>. Hierarchical degradation models can
be fitted using nonlinear mixed-effects model packages as a back end as
described by Ranke et al. (2021) <doi:10.3390/environments8080071>. Please
note that no warranty is implied for correctness of results or fitness for a
particular purpose.

<dl><dt>object</dt>
<dd>The fitted saem.mmkin object</dd>
<dt>level</dt>
<dd>The confidence level. Must be the default of 0.95 as this is what
is available in the saemix object</dd>
<dt>backtransform</dt>
<dd>In case the model was fitted with mkin transformations,
should we backtransform the parameters where a one to one correlation
between transformed and backtransformed parameters exists?</dd>
<dt>...</dt>
<dd>For compatibility with the generic method</dd></dl>
