Insert and fill missing panel years — panel

Inserts missing years within eligible observed ID spans and fills numeric fields from the nearest observations bracketing each gap. See panel_complete() for the researcher-facing wrapper that completes every segmented span.

Usage

panel_impute(
  data,
  classification = NULL,
  types = "persistent",
  method = c("mean", "interpolate", "locf", "nocb"),
  max_gap_size = Inf,
  max_gap_count = Inf,
  vars = NULL,
  time = "TAX_YEAR",
  id = "EIN2",
  as_integers = FALSE
)

Arguments

data: A panel data frame.
classification: Optional classification from panel_describe().
types: Panel types eligible for imputation. Default "persistent" (the panel-spanning type); only segmented organizations actually have interior years to fill.
method: Fill method: "mean" (average of the bracketing observations), "interpolate" (linear between them), "locf" (carry the prior value forward), or "nocb" (carry the next value backward).
max_gap_size: Maximum single gap length.
max_gap_count: Maximum number of gaps per ID.
vars: Numeric variables to fill; NULL selects numeric non-key fields.
time: Panel-time column.
id: Panel-ID column.
as_integers: Round values for originally integer fields.

Value

A panel with inserted rows identified by imputed_row.
