Runs alignment optimizer

Description

Not generally intended to be used on its own, but exported anyway for didactic purposes.

Usage

align.optim(
  stacked,
  n,
  estimator,
  nstarts = 50,
  ncores = 3,
  hyper.first,
  center.means,
  eps.alignment,
  clf.ignore.quantile,
  verbose
)

Arguments

stacked	Stacked parameter estimates from stackEstimates
n	Sample size in each group
estimator	See Alignment documentation.
nstarts	Number of starting values for alignment; default is 10
ncores	See Alignment documentation.
hyper.first	See Alignment documentation.
center.means	See Alignment documentation.
eps.alignment	See Alignment documentation.
clf.ignore.quantile	See Alignment documentation.
verbose	See Alignment documentation.

Details

See example for Alignment for examples

Value

A list of results from multiple runs of the alignment optimizer:

• mv Means and variances from each alignment run.

• parout A table of outputs from link[stats]{optim} containing the function values, convergence information, and resulting estimates of means and variances from each run.

• nFailedRuns The number of runs that failed to complete. An error is returned if no runs fail.
