What is AdstockITSA?
- In marketing science, two forces often run in parallel but rarely meet:
- Adstock – the memory effect of advertising, how impressions linger and decay over time.
- Interrupted Time Series Analysis (ITSA) – A technique for identifying the true effect of interventions.
- At Aryma Labs, we have fused the two, Adstock + ITSA = AdstockITSA.
- Why is this a game changer?
- Because interventions (campaign launches, price changes, new product launches) don’t happen in a vacuum. Their effects are sticky. Advertising doesn’t just stop impacting when the campaign ends, it decays. ITSA by default assumes sharp interventions. Adstock smooths that, giving us a more realistic lens into how interventions actually play out in the market.
Key Use Case of AdstockITSA
- Measure impact where awareness is built via campaigns that linger in consumer memory.
- Understanding promotion effectiveness where halo/adstock effects stretch beyond the promo window.
- Understand the effect of launching new product ranges on sales.
- Evaluating brand-building campaigns that have long-tail effects not captured by naïve pre-post comparisons.
- Disentangling seasonality vs true intervention lift when carryover effects overlap.
Why AdstockITSA is a Game Changer?
Self Serve App
The Campaign windows
Real marketing campaigns often follow a start-stop pattern. With campaign windows feature, identify if the campaigns had an effect in that particular time period.
Measure impact of Adstock
Evaluate the lingering impact of marketing campaigns. The tool automatically and intelligently selects the best adstock method (Weibull or Geometric or Hill) based on data.
Intuitive visualization:
Auto-generated plots show treated vs. control series with shaded intervention zones. Effect-significance annotated right on the timeline.
Layman Summaries
Don't have statistics / Econometrics background, don't worry. Our Layman explanation provides you with enough details without getting into the nitty gritty.
Expert Summaries
If you are a statistician / Econometrician, the tool provides in-depth report of the analysis which you can verify and draw insights from.
One-Click Export
Instantly download model summaries and charts as PDFs — perfect for reports, decks and importantly quick decision making.
Audit-Ready Assumption Checklists
Displays and documents key ITSA assumptions that goes into each experiment:Linearity within segments, No concurrent interventions, Consistent measurement, Independent residuals and Sufficient pre/post data.
