weibullDecay: Weibull decay function

In PathwaySpace: Spatial Projection of Network Signals along Geodesic Paths

Weibull decay function

Description

The weibullDecay function is used by PathwaySpace's methods for signal convolution and projection.

Usage

weibullDecay(x, signal = 1, decay = 0.001, shape = 1.05)

Arguments

x	A numeric vector of distances (in [0,1]).
signal	A single numeric value representing a signal.
decay	A decay factor (in [0,1]). This term indicates how much the signal decreases as a function of distance in pathway space. For example, at a specific distance defined by the pdist parameter (see circularProjection), the signal intensity will be the initial signal multiplied by decay.
shape	A parameter (>=1) of a Weibull function. When shape=1 the Weibull decay follows an exponential decay. When shape>1 the function is first convex, then concave with an inflection point.

Value

A numeric vector; if missing 'x', it will return decay function.
