GeoExperimentPreanalysisData: Creates a GeoExperimentPreanalysisData object.

In google/GeoexperimentsResearch: Geo Experiments

Description

Creates a GeoExperimentPreanalysisData object.

Usage

GeoExperimentPreanalysisData(obj, period.lengths, geos, recycle = TRUE)

Arguments

obj	a GeoTimeseries object.
period.lengths	an integer-valued vector of length 2 or 3, denoting the lengths (in days) of pre-period, test, and the (optional) cooldown periods, respectively. The test period must be at least 7 days; the pre-period must be at least as long as the test period. The cooldown period can be 0 or more days; if it is zero, it will be ignored as if there were only 2 periods.
geos	(GeoStrata or GeoAssignment object) object to use for choosing the geo groups at the time of simulating (using SimulateGeoExperimentData); if 'geos' is a GeoAssignment object, then the geo assignment will be fixed; iteration; if 'geos' is a GeoStrata, then the geo assignment will be generated by a call to 'Randomize'.
recycle	(flag) if TRUE, creates an augmented data set in order to create a larger time series, reusing data from the head of the time series.

Value

A GeoExperimentPreanalysis object, which inherits from GeoExperimentData, with NAs in 'geo.group', 'period', and 'assignment'. The default treatment assignment (spend change only for period 1 and group 2) is stored into the object.

Note

A GeoExperimentPreanalysisData object stores a historical data set and the information about the length of the experiment periods. It is used as the generator of pseudo-data sets for simulation purposes. See also: 'SimulateGeoExperimentData' to generate a GeoExperimentData object.
