Geometric Adstock Weights

geometric_adstock_weights is a function that is called to generate a vector of weights that define how media impressions will be decayed in present and carried over into the future.

Usage

geometric_adstock_weights(decay = 0.5, max_carryover = 12, normalize = TRUE)

Arguments

decay

decay rate

max_carryover

maximum carryover

normalize

should the result be scaled?

Value

a numeric vector of weights of length (max_carryover)
