Predict Method for beezdemand_fixed

Description

Predict Method for beezdemand_fixed

Usage

## S3 method for class 'beezdemand_fixed'
predict(
  object,
  newdata = NULL,
  type = c("response", "link"),
  se.fit = FALSE,
  interval = c("none", "confidence"),
  level = 0.95,
  ...
)

Arguments

object	A beezdemand_fixed object.
newdata	A data frame containing a price column matching the fitted object's x_var. If NULL, uses the unique observed prices when available.
type	One of "response" (default) or "link".
se.fit	Logical; if TRUE, includes a .se.fit column (currently NA because vcov is not available from legacy fixed fits).
interval	One of "none" (default) or "confidence". When requested, .lower/.upper are returned as NA because vcov is unavailable.
level	Confidence level when interval = "confidence". Currently used only for validation.
...	Unused.

Value

A tibble containing the original newdata columns, plus .fitted and, when requested, .se.fit and .lower/.upper. If newdata does not include an id column, predictions are returned for all subjects (cross product of newdata × subjects) unless k is subject-specific (k = "ind").
