Description

Auxiliary for Controlling pclm2D Fitting

Usage

control.pclm2D(lambda     = c(1, 1),
               kr         = 7,
               deg        = 3,
               int.lambda = c(0.1, 1e+3),
               diff       = 2,
               opt.method = c("BIC", "AIC"),
               max.iter   = 1e+3,
               tol        = 1e-3)

Arguments

lambda

Smoothing parameter to be used in pclm estimation. If lambda = NA an algorithm will find the optimal values.

kr

Knot ratio. Number of internal intervals used for defining 1 knot in B-spline basis construction. See MortSmooth_bbase.

deg

Degree of the splines needed to create equally-spaced B-splines basis over an abscissa of data.

int.lambda

If lambda is optimized an interval to be searched needs to be specified. Format: vector containing the end-points.

diff

An integer indicating the order of differences of the components of PCLM coefficients. Default value: 2.

opt.method

Selection criterion of the model. Possible values are "AIC" and "BIC". Default: "BIC".

max.iter

Maximal number of iterations used in fitting procedure.

tol

Relative tolerance in PCLM fitting procedure. Default: 0.1% i.e. the estimated aggregate bins should be in the 0.1% error margin.

Value

A list with exactly eight control parameters.
