sd_scale: Sigma scaling function

In ecostatscale: Statistical Scaling Functions for Ecological Systems

Sigma scaling function

Description

Extrapolate disturbance standard deviation observed at spatial or ecological scale b to a different scale, B (inversely related to resistance). Equivalent to Eq.7b in the main text.

Usage

sd_scale(msd_b, murho_b, mucov_b = NULL, b = 1, B)

Arguments

msd_b	Mean disturbance standard deviation observed at scale b.
murho_b	Mean Pearson correlation coefficient of disturbances observed at scale b, calculated as mucov_b/mvar_b. If NULL, mucov_b is used instead.
mucov_b	Mean covariane of disturbances observed at scale b. Ignored if mrho_b is not NULL. Defaults to NULL.
b	Size of observed scale. Defaults to 1.
B	Size of desired scale for extrapolation.

Value

Extrapolated disturbance standard deviation at scale B.

Examples

#extrapolate from scale of 1 to 10 - e.g. from a 1m2 patch to a 10m2 patch
sd_scale(msd_b = 1, murho_b = 0.5, b = 1, B = 10)
