Memory kernel
Description
Probability density function and complementary cumulative distribution function for the human reaction time.
Usage
memory.pdf(t, theta = 0.2314843, cutoff = 300, c = 0.0006265725)
memory.ccdf(t, theta = 0.2314843, cutoff = 300, c = 0.0006265725)
Arguments
t |
time |
theta |
exponent of the power law |
cutoff |
the cutoff value where the density changes from constant to power law |
c |
the constant density when t is less than the cutoff |
Details
default values are measured from a real Twitter data set.
Value
the density at t
memory.pdf
returns the density function at t.
memory.ccdf
returns the ccdf (probabilty of greater than t).
