Is it possible to use the R package CausalImpact (Brodersen et. al, 2015) to estimate the incremental lift of running a local TV ad campaign in Iowa City,IA? We are also running national TV ads across the USA including Iowa City,IA.
The Brodersen et al. paper explains the use of the package along with Geo experiments, where multiple treated DMAs are summed up into a single treated unit, but there isn't any clarity in cases where we just have one treated DMA.
