MultiCellWinner: Multi-Cell Winner Declaration Method for Market Selection.

In facebookincubator/GeoLift: Synthetic Control Method to Calculate Lift at a Geo Level

Multi-Cell Winner Declaration Method for Market Selection.

Description

MultiCellWinner explores the likelihood of observe a winning cell for a given Multi-Cell Market Selection. This method analyzes all pairwise comparisons to determine how much larger the incremental ROAS (iROAS) must be for a cell to be declared the winner based on a statistical significance test.

Usage

MultiCellWinner(
  multicell_power_obj,
  effect_size = NULL,
  geolift_type = "standard",
  ROAS = seq(0, 5, 0.05),
  alpha = 0.1,
  method = "conformal",
  stat_test = "Total"
)

## S3 method for class 'MultiCellWinner'
print(x, ...)

Arguments

multicell_power_obj	A MultiCellPower object.
effect_size	A numeric value representing the lift to be simulated across all cells. If not specified (default), the algorithm will use the largest lift needed to obtain a well-powered test across all cells.
geolift_type	String that specifies the type of GeoLift test to be performed: "standard": Standard GeoLift test where ads are shown to test regions. Defualt. "inverse": Inverse or Negative GeoLift test where the test group is holded-out from the treatment.
ROAS	Vector of incremental Return on Ad Spend (iROAS) values to assess. Set to seq(0,5,0.05) by default.
alpha	Significance Level. By default 0.1.
method	A string indicating the method used to calculate the aggregate ATT Confidence Intervals. "conformal": Conformal Inference. Defualt. "jackknife+": Jackknife+ (exclusively for stat_test = "Total").
stat_test	A string indicating the test statistic. "Total": The test statistic is the sum of all treatment effects, i.e. sum(abs(x)). Default. "Negative": One-sided test against positive effects i.e. -sum(x). Recommended for Negative Lift tests. "Positive": One-sided test against negative effects i.e. sum(x). Recommended for Positive Lift tests.
x	MultiCellWinner()
...	Optional arguments

Value

A list with two objects:

• "results": Data frame with all pairwise comparisons and required iROAS needed to declare a winner for the multi-cell test.

• "simulations": The complete data frame of all simulations for all pairwise comparisons.
