Arguments

binary

Forces the outcomeCount to be 0 or 1 (use for binary prediction problems)

includeAllOutcomes

(binary) indicating whether to include people with outcomes who are not observed for the whole at risk period

firstExposureOnly

Should only the first exposure per subject be included? Note that this is typically done in the createStudyPopulation function,

washoutPeriod

The mininum required continuous observation time prior to index date for a person to be included in the cohort.

removeSubjectsWithPriorOutcome

Remove subjects that have the outcome prior to the risk window start?

priorOutcomeLookback

How many days should we look back when identifying prior outcomes?

requireTimeAtRisk

Should subject without time at risk be removed?

minTimeAtRisk

The minimum number of days at risk required to be included

riskWindowStart

The start of the risk window (in days) relative to the index date (+ days of exposure if the addExposureDaysToStart parameter is specified).

startAnchor

The anchor point for the start of the risk window. Can be "cohort start" or "cohort end".

riskWindowEnd

The end of the risk window (in days) relative to the index data (+ days of exposure if the addExposureDaysToEnd parameter is specified).

endAnchor

The anchor point for the end of the risk window. Can be "cohort start" or "cohort end".

restrictTarToCohortEnd

If using a survival model and you want the time-at-risk to end at the cohort end date set this to T

Value

A list containing all the settings required for creating the study population
