deconvolve {lowpassFilter}R Documentation

Deconvolution of a single jump / isolated peak

Description

For developers only; computes the deconvolution of a single jump or an isolated peak assuming that the observations are lowpass filtered. More details are given in (Pein et al., 2018).

Usage

.deconvolveJump(grid, observations, time, leftValue, rightValue,
                typeFilter, inputFilter, covariances) 
.deconvolvePeak(gridLeft, gridRight, observations, time, leftValue, rightValue,
                typeFilter, inputFilter, covariances, tolerance)

Arguments

grid, gridLeft, gridRight

numeric vectors giving the potential time points of the single jump, of the left and right jump points of the peak, respectively

observations

a numeric vector giving the observed data

time

a numeric vector of length length(observations) giving the time points at which the observations are observed

leftValue, rightValue

single numerics giving the value (conductance level) before and after the jump / peak, respectively

typeFilter, inputFilter

a description of the assumed lowpass filter, usually computed by lowpassFilter

covariances

a numeric vector giving the (regularized) covariances of the observations

tolerance

a single numeric giving a tolerance for the decision whether the left jump point is smaller than the right jump point

Value

For .deconvolveJump a single numeric giving the jump point. For .deconvolvePeak a list containing the entries left, right and value giving the left and right jump point and the value of the peak, respectively.
