getFixedEffectsByAutoInit

Compute initial values for fixed-effect population parameters. The values are returned in the same format as getPopulationParameterInformation and can be passed to setPopulationParameterInformation to set the inital values.

Usage

R
getFixedEffectsByAutoInit(ids = NULL)

Arguments

ids

(integer) [optional] if included, a vector of indices of individuals to use to estimate initial values, otherwise all individuals are included (can be used to speed up estimation in the case of many individuals)

See also

getPopulationParameterInformation to get the current population parameter information, including initial values
setPopulationParameterInformation to set the population parameter information (e.g. with the results of this method)
setInitialEstimatesToLastEstimates to set the population parameter initial values to the last estimated values

Examples

R
initializeLixoftConnectors("monolix")
loadProject(file.path(getDemoPath(), "1.creating_and_using_models", "1.1.libraries_of_models", "theophylline_project.mlxtran"))

initValues <- getFixedEffectsByAutoInit()
setPopulationParameterInformation(initValues)

# restrict initial value estimation to only certain individuals
# (most useful when there are many similar individuals and estimation takes a long time)
initValues <- getFixedEffectsByAutoInit(ids = 1:10)
