lifetimeValue property

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
