Usage

## S3 method for class 'nmfkc.ecv'
print(x, ...)

## S3 method for class 'nmfkc.ecv'

## S3 method for class 'nmfkc.bicv'
print(x, ...)

## S3 method for class 'nmfkc.bicv'
plot(
  x,
  main = "nmfkc bi-cross-validation",
  ylab = "sigma (held-out RMSE)",
  ...
)

## S3 method for class 'nmfkc.cv'
print(x, ...)

## S3 method for class 'nmfkc.cv'
plot(
  x,
  main = "nmfkc CV: per-fold held-out loss",
  ylab = "objfunc (block)",
  ...
)

Arguments
