Defines a cohort group. For example:

"cohortGroup": {
  "cohorts": [{
    "name": "cohort 1",
    "type": "FIRST_VISIT_DATE",
    "dateRange": { "startDate": "2015-08-01", "endDate": "2015-08-01" }
  },{
    "name": "cohort 2"
     "type": "FIRST_VISIT_DATE"
     "dateRange": { "startDate": "2015-07-01", "endDate": "2015-07-01" }
  }]
}

Attributes

• cohorts (type: list(GoogleApi.AnalyticsReporting.V4.Model.Cohort.t), default: nil) - The definition for the cohort.

• lifetimeValue (type: boolean(), default: nil) - Enable Life Time Value (LTV). LTV measures lifetime value for users acquired through different channels. Please see: Cohort Analysis and Lifetime Value If the value of lifetimeValue is false:

  • The metric values are similar to the values in the web interface cohort report.
  • The cohort definition date ranges must be aligned to the calendar week and month. i.e. while requesting ga:cohortNthWeek the startDate in the cohort definition should be a Sunday and the endDate should be the following Saturday, and for ga:cohortNthMonth, the startDate should be the 1st of the month and endDate should be the last day of the month.

  When the lifetimeValue is true:

  • The metric values will correspond to the values in the web interface LifeTime value report.
  • The Lifetime Value report shows you how user value (Revenue) and engagement (Appviews, Goal Completions, Sessions, and Session Duration) grow during the 90 days after a user is acquired.
  • The metrics are calculated as a cumulative average per user per the time increment.
  • The cohort definition date ranges need not be aligned to the calendar week and month boundaries.
  • The viewId must be an app view ID
