findBinaryTreated function

findBinaryTreated

findBinaryTreated is used to identify t,id pairs of units for which a matched set might exist. More precisely, it finds units for which at time t, the specified treatment has been applied, but at time t - 1, the treatment has not.

findBinaryTreated(
  dmat,
  qoi.in,
  treatedvar,
  time.var,
  unit.var,
  hasbeensorted = FALSE
)

Arguments

• dmat: Data frame or matrix containing data used to identify potential treated units. Must be specified in such a way that a combination of time and id variables will correspond to a unique row. Must also contain at least a binary treatment variable column as well.
• treatedvar: Character string that identifies the name of the column in dmat that provides information about the binary treatment variable
• time.var: Character string that identifies the name of the column in dmat that contains data about the time variable. This data must be integer that increases by one.
• unit.var: Character string that identifies the name of the column in dmat that contains data about the variable used as a unit id. This data must be integer
• hasbeensorted: variable that only has internal usage for optimization purposes. There should be no need for a user to toggle this

Returns

findBinaryTreated returns a subset of the data in the dmat data frame, containing only treated units for which a matched set might exist
