Edit an existing smoothing step in a refinement workflow — edit

edit_smoothing() modifies a previously added smoothing step in a rating_refinement object. The actual smoothing is only re-applied when refit() is called.

Usage

edit_smoothing(
  model,
  variable = NULL,
  step = NULL,
  x1,
  x2,
  overwrite_y1 = NULL,
  overwrite_y2 = NULL,
  knots_x = NULL,
  knots_y = NULL,
  allow_extrapolation = FALSE,
  extrapolation_break_size = NULL
)

Arguments

model: Object of class rating_refinement, smooth or restricted.
variable: Character. The x_cut variable of the smoothing step to edit.
step: Optional numeric index of the step to edit.
x1, x2: Numeric. Start and end of the interval over which the smoothing should be modified.
overwrite_y1, overwrite_y2: Optional numeric. Overrides for the smoothed values at x1 and x2.
knots_x, knots_y: Optional numeric vectors of equal length.
allow_extrapolation: Logical.
extrapolation_break_size: Numeric scalar (> 0) or NULL.

Value

Object of class rating_refinement.
