Maximum Percentage Residual
Description
Function to determine the maximum percentage residual from the fitted value, i.e. the maximum
value of a residual as a percentage of its fitted value. This is useful for obtaining estimates
of t*.
Usage
maxpercres(outputobject)
Arguments
outputobject
The output of a kinetic model, including a fit object outputobject$fit
Value
The maximum percentage of the fitted value of a residual in the fit.

Examples
# Note: Reference region models, and irreversible binding models, should not
# be used for PBR28 - this is just to demonstrate function
data(pbr28)
t_tac <- pbr28$tacs[[2]]$Times / 60
reftac <- pbr28$tacs[[2]]$CBL
roitac <- pbr28$tacs[[2]]$STR
weights <- pbr28$tacs[[2]]$Weights
refloganout <- refLogan(t_tac, reftac, roitac, 0.1, tstarIncludedFrames = 9)
maxpercres(refloganout)
