This function optimizes the parameter values of the Westcott adjustment.

Usage

optim.w(
  trait,
  geno,
  replicated,
  ck1,
  ck2,
  row,
  col,
  ncb,
  nrs,
  method,
  ind,
  p,
  opt = c("F.value", "MSE", "CV"),
  dfr
)

Arguments

trait	The name of the column for the trait to adjust.
geno	The name of the column that identifies the genotypes.
replicated	A yes/no column to identify replicated genotypes.
ck1	Name of check 1.
ck2	Name of check 2.
row	The name of the column that identifies the rows.
col	The name of the column that identifies the columns.
ncb	Number of columns between two check columns.
nrs	Set of values for the nrs param on aj.w.
method	Set of values for the method param on aj.w.
ind	Set of values for the ind param on aj.w.
p	Set of values for the p param on aj.w.
opt	Criteria for optimization, F.value, MSE or CV. See details.
dfr	The name of the data frame.

Details

If optim = F.value then the F value for ANOVA is maximized. If optim = MSE then the MSE is minimized. If optim = CV then the CV is minimized.

Value

It returns optimal set of values under the selected criteria.
