sd_scale | R Documentation |
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.
sd_scale(msd_b, murho_b, mucov_b = NULL, b = 1, B)
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. |
Extrapolated disturbance standard deviation at scale B.
#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)
