In ashtonwiens/gp.nonrigid.registration: An R package for rigid and nonrigid registration of spatial surfaces

Description

Used as the objective function in a call to optim

Usage

## S3 method for class 'deformation.penalized'
logLik(p, nu, grd, grd2, lambda,
  int = NULL, kappa = NULL, pen.type = "L2")

Arguments

p	covariance parameters (range, sill and nugget variances) and transformation parameters (x, y, z translations and 2d rotation) to be optimized over
nu	fixed smoothness parameter of the Matern covariance function
grd	three column data set 1
grd2	three column data set 2
lambda	multiplicative tuning parameter in the penalty term
pen.type	type of penalty term to apply ('L1', 'L2', 'elastic', or 'none')

Value

the value of the penalized likelihood function
