prd_err function

Error of Model's Prediction

The maximum error in the model's predicted azimuth given the Pole of rotations uncertainty and distance of the data point to the pole.

prd_err(dist_PoR, sigma_PoR = 1)

Arguments

• dist_PoR: Distance to Euler pole (great circle distance, in degree)
• sigma_PoR: uncertainty of the position of the Pole of rotation (in degree).

Returns

numeric vector. The maximum error for azimuths prediction (in degree)

Examples

prd_err(67, 1)

# San Andreas example:
data("nuvel1")
por <- subset(nuvel1, nuvel1$plate.rot == "na") # North America relative to Pacific plate
data("san_andreas")
d <- PoR_distance(san_andreas, por)
prd_err(d)
