create the study population settings

Description

create the study population settings

Usage

createStudyPopulationSettings(
  binary = T,
  includeAllOutcomes = T,
  firstExposureOnly = FALSE,
  washoutPeriod = 0,
  removeSubjectsWithPriorOutcome = TRUE,
  priorOutcomeLookback = 99999,
  requireTimeAtRisk = T,
  minTimeAtRisk = 364,
  riskWindowStart = 1,
  startAnchor = "cohort start",
  riskWindowEnd = 365,
  endAnchor = "cohort start",
  restrictTarToCohortEnd = F
)

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
