model2.Excess.Inv2: model2.Excess.Inv2

In stw32/PulseWaveform: Extraction of Photoplethysmography Waveform Features and Decomposition Modeling of Pulse Waveforms

model2.Excess.Inv2

Description

model2.Excess.Inv2 adds the model's decay element to its excess element. It is used within model2.Rebuild2 as part of the construction of a modelled waveforms from inputted model parameters.

Usage

model2.Excess.Inv2(time,excess,offset,baselineStart,baselineEnd,timeBase,config.rate)

Arguments

time	x coordinates of a particular segment of the PPG time series
excess	segment corresponding to excess element of reconstructed waveform
offset	the y value of the data point immediately preceding the inputted segment of the ppg time series
baselineStart	the y-value towards which the first baseline decays
baselineEnd	the y-value towards which the second baseline decays
timeBase	the point in time (x value) when baseline 1 switches to baseline 2, defined as the D (2nd reflectance) peak timing
config.rate	decay rate parameter

Value

result

a modelled waveform with combined excess and decay elements

Examples

result <- model2.Excess.Inv2(xy[,1],result,offset,params[1],params[2],
                                 params[3]+1*params[6],
                                 config.rate = params[12])
