This function uses saemix::saemix() as a backend for fitting nonlinear mixed
effects models created from mmkin row objects using the Stochastic Approximation
Expectation Maximisation algorithm (SAEM).

Arguments
| object | An mmkin row object containing several fits of the same mkinmod model to different datasets |
|---|---|
| ... | Further parameters passed to saemix::saemixModel. |
| transformations | Per default, all parameter transformations are done in mkin. If this argument is set to 'saemix', parameter transformations are done in 'saemix' for the supported cases. Currently this is only supported in cases where the initial concentration of the parent is not fixed, SFO or DFOP is used for the parent and there is either no metabolite or one. |
| degparms_start | Parameter values given as a named numeric vector will be used to override the starting values obtained from the 'mmkin' object. |
| test_log_parms | If TRUE, an attempt is made to use more robust starting values for population parameters fitted as log parameters in mkin (like rate constants) by only considering rate constants that pass the t-test when calculating mean degradation parameters using mean_degparms. |
| conf.level | Possibility to adjust the required confidence level for parameter that are tested if requested by 'test_log_parms'. |
| solution_type | Possibility to specify the solution type in case the automatic choice is not desired |
| nbiter.saemix | Convenience option to increase the number of iterations |
| control | Passed to saemix::saemix. |
| fail_with_errors | Should a failure to compute standard errors from the inverse of the Fisher Information Matrix be a failure? |
| verbose | Should we print information about created objects of type saemix::SaemixModel and saemix::SaemixData? |
| quiet | Should we suppress the messages saemix prints at the beginning and the end of the optimisation process? |
| x | An saem.mmkin object to print |
| digits | Number of digits to use for printing |
Value
An S3 object of class 'saem.mmkin', containing the fitted saemix::SaemixObject as a list component named 'so'. The object also inherits from 'mixed.mmkin'.
An saemix::SaemixModel object.
An saemix::SaemixData object.
Details
An mmkin row object is essentially a list of mkinfit objects that have been obtained by fitting the same model to a list of datasets using mkinfit.
Starting values for the fixed effects (population mean parameters, argument
psi0 of saemix::saemixModel() are the mean values of the parameters found
using mmkin.
