A function that will convolve over the one dimensional vector of raw impressions over time and apply the adstock weights.

Usage

convolve_adstock_weights(x, w)

Arguments

x

vector

w

weights

Value

a numeric vector of length(x) with adstock transformed media impressions.

Examples

data(mmm_imps)
x <- mmm_imps$mi_banners
w <- geometric_adstock_weights()
a <- convolve_adstock_weights(x, w)
