mean_degparms: Calculate mean degradation parameters for an mmkin row object

In mkin: Kinetic Evaluation of Chemical Degradation Data

Calculate mean degradation parameters for an mmkin row object

Description

Calculate mean degradation parameters for an mmkin row object

Usage

mean_degparms(
  object,
  random = FALSE,
  test_log_parms = FALSE,
  conf.level = 0.6,
  default_log_parms = NA
)

Arguments

object	An mmkin row object containing several fits of the same model to different datasets
random	Should a list with fixed and random effects be returned?
test_log_parms	If TRUE, log parameters are only considered in the mean calculations if their untransformed counterparts (most likely rate constants) pass the t-test for significant difference from zero.
conf.level	Possibility to adjust the required confidence level for parameter that are tested if requested by 'test_log_parms'.
default_log_parms	If set to a numeric value, this is used as a default value for the tested log parameters that failed the t-test.

Value

If random is FALSE (default), a named vector containing mean values of the fitted degradation model parameters. If random is TRUE, a list with fixed and random effects, in the format required by the start argument of nlme for the case of a single grouping variable ds.
