getspeed: Average speed of Brownian motion particle

Description Usage Arguments

View source: R/sigma_speed.r

Description

Calculates the average speed E(displacement/time) of a particle doing Brownian motion with movement rate paramter sigmarate, over a time period lag. Uses the fact that the expected value of a Chi random variable is sqrt(2)/gamma(0.5).

Usage

1
getspeed(sigmarate, lag = 1)

Arguments

sigmarate

The Brownian motion with movement rate paramter

lag

The time over which the average speed is required.
