Impute actual time using nominal time when actual is unavailable

Impute actual time using nominal time when actual is unavailable

Usage

impute_time_act_nom(actual, nominal)

Arguments

actual, nominal

Actual and nominal times as numeric vectors

Value

actual with missing values imputed, as feasible, based on nominal times.

Details

The rules used are the following, in order.

• If actual is not missing, use it.

• If there is at least one non-missing actual for a given nominal, take the median actual from the nominal.

• If for a missing actual time, the actual time values are in order compared to the nominal time:

  • If both directions with nominal and actual times (before and after) are within 24 hours, interpolate between.

  • If only one direction with nominal and actual times (before or after) is within 24 hours, extrapolate in that direction ignoring the other direction.
