BasisDimension.Choice: Choice of the B-spline dimension

In sysbioTurin/connector: Fitting and clustering of longitudinal data

Choice of the B-spline dimension

Description

Generates a line plot reporting the cross-validated loglikelihood value for each number of knots. In details, for each number of knots 10\

Usage

BasisDimension.Choice(data, p, save = FALSE, path = NULL, Cores = 1)

Arguments

data	CONNECTORList. (see DataImport)
p	The vector of the dimension of the natural cubic spline basis.
save	If TRUE then the plot is saved into a pdf file.
path	The folder path where the plot will be saved. If it is missing, the plot is saved in the current working directory.
Cores	Number of cores to parallelize computations.

Value

DimensionBasis.Choice returns line plot of the cross-validated loglikelihood for each value of p, in grey the result of all ten repetitions of the likelihood calculation and in black the mean of them.
