saemix_data(object, covariates = NULL, verbose = FALSE, ...)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, i.e. (as of version 1.1.2) SFO, FOMC, DFOP and HS without fixing
parent_0, and SFO or DFOP with one SFO metabolite.- error_model
Possibility to override the error model used in the mmkin object
- 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
- covariance.model
Will be passed to
saemix::saemixModel(). Per default, uncorrelated random effects are specified for all degradation parameters.- omega.init
Will be passed to
saemix::saemixModel(). If using mkin transformations and the default covariance model with optionally excluded random effects, the variances of the degradation parameters are estimated using mean_degparms, with testing of untransformed log parameters for significant difference from zero. If not using mkin transformations or a custom covariance model, the default initialisation of saemix::saemixModel is used for omega.init.- covariates
A data frame with covariate data for use in 'covariate_models', with dataset names as row names.
- covariate_models
A list containing linear model formulas with one explanatory variable, i.e. of the type 'parameter ~ covariate'. Covariates must be available in the 'covariates' data frame.
- no_random_effect
Character vector of degradation parameters for which there should be no variability over the groups. Only used if the covariance model is not explicitly specified.
- error.init
Will be passed to
saemix::saemixModel().- nbiter.saemix
Convenience option to increase the number of iterations
- control
Passed to saemix::saemix.
- 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.
