In google/GeoexperimentsResearch: Geo Experiments

Description

Computes the weights to be used in the weighted linear model used to estimate ROAS.

Usage

ComputeLinearModelWeights(response, power = 2)

Arguments

response	a vector of the response in the pre period. Length equal to the number of geos. Must be all nonnegative.
power	default power to which 'response' is raised to. Can be overridden by setting the global option 'geoexperiments.gbr1.weight.power'. Must be nonnegative.

Value

A vector of weights of the same length as 'response'. Data points with response == 0 have weight NA (indicating these need to be taken special care of). There is an attribute 'power' corresponding to the exponent used.

Note

If a component of 'response' tends to infinity, the corresponding weight tends to 0 (i.e., the corresponding data point is ignored).
