  2. 2. Precision Marketing AnalyticsWorking with time-varying parametersMeasuring the impact of marketing Until recently marketers relied heavily The techniques and benefits of TVP modeling on constant parameters regression (CPR) are well acknowledged by scholars andon sales has long been seen as modeling to understand the impact of analysts in various industries. For instance,an essential planning tool for marketing investments on sales. Ads were the National Institute of Commoditymarketers. Understanding the bought on long lead times, the analysis Promotion Research and Evaluation appliedreturn on marketing investment of data was on a six-month cycle or more, this approach to the New York City’s fluid(MROI) of one promotional activity and media plans were prepared on an milk campaign data to understand the annual basis.

  3. 3. The ripple effectAt a time when chief marketing officers(CMOs) are under pressure to justify MROI,the TVP model helps increase accountabilityand drive marketing spend to higher levelsof incremental value per dollar invested.This approach ensures precision of dataand greater transparency in measuring theeffectiveness of marketing initiatives indriving sales across media channels—keyinformation that the finance departmentrequires for business planning. In fact, asother departments become aware of theincreased insight that more granular databrings to investment decisions, the rippleeffects of this approach are likely to befelt throughout the company.
  4. 4. Time-varying Parameters— A working exampleTo better understand the hidden dimensions and multiple benefitsof TVP modeling, it is helpful to take an example: SuperiorBuy—afictitious FMCG company with more than 1500 stores and 50Designated Market Areas (DMAs).Assume that the marketing department Going beyond consistent baselineat SuperiorBuy ran a series of marketing Available studies show that both approachescampaigns for two years across a number of are able to capture a company’s baselineoffline and online media channels. At the end sales (that is, loyal sales) accurately.of the campaign, the CMO at SuperiorBuy In addition, the CPR modeling approachwanted to quantify the effectiveness of its provides an acceptable estimate of themarketing activities across media channels weekly average sales attributed to marketingon a weekly basis over the two-year period. activities at a regional or national level.Based on the insights gained, he wanted The TVP modeling approach, however, goes ato plan the future marketing activities and step further and provides precise estimatesallocate appropriate budget to various media of the effectiveness of marketing activitieschannels. Which approach should the CMO across media channels in driving sales atuse to achieve his objective—TVP or CPR? a local level on a week by week basis.DefinitionsConstant Parameters Regression (CPR) model.A statistical (regression) model which provides advertising effectivenessestimates under the assumption that effectiveness is constant over time.Time-varying Parameters (TVP) model.A statistical (regression) model where multiple instances of advertisingeffectiveness (i.e. regression coefficients) can be defined over time.
  5. 5. Calibrating effectiveness of Figure 1a: SuperiorBuy actual sales over two year period showing Circular contribution (yellow area) to sales—CPR Approachmarketing activities in driving salesAs SuperiorBuy has a large number of storesacross multiple markets with differentlocal sales patterns, it is important that theCMO gain insight into the effectiveness ofmarketing activities across media channels Salesat a granular, rather than regional or 1 2national levels. As revealed in Figures 1aand 1b, a comparative analysis shows thatin such instances, the TVP model is moreappropriate than the CPR technique.Average versus actual MonthsAs reflected in Figures 1a and 1b, actualsales (white dotted line) showed a dramaticdrop on a number of occasions, for example Figure 1b: SuperiorBuy actual sales over two year period showing Circular contributionafter the Holiday Sales or Spring break, (yellow area) to sales—TVP Approachwhen SuperiorBuy stopped investing in oneof its key promotional activities, Circulars.The CPR modeling approach is unable tocapture the dip in sales (Figure 1a—1); onthe contrary, it gives the impression that SalesCirculars continued to contribute the most 1 2to sales. This is because the CPR modelprovides an estimate of sales activityby averaging results across the twoyear period, thereby smoothing out anysubstantial change in sales at a local level.By providing skewed estimates, the CPR Monthstechnique masks the true relationshipbetween marketing activities and both Actual salesweekly and annual sales. Sales attributed to circularsBy contrast, the TVP modeling approachreveals that when SuperiorBuy stopped S ales attributed to other marketing activitiesinvesting in Circulars, sales from thismedia driver came to a complete stop(Figure 1b—1). It also reflects thatinvestment in other marketing activities(orange area) continued to contribute tosales but by a much smaller proportionthan before. This type of additional insightcomes from the ability of the TVP modelto quantify uplifts and dips on a week byweek basis.
  6. 6. Media Driver Sensitivity Sales Figure 2: Long term sales quantified by CPR and TVP modelingWhen SuperiorBuy invested in several 4,000media drivers, leading to a boost in actualsales, for example, before the Holidays, Long term 3,500the CPR modeling approach reveals that average salesCirculars contributed only marginally to contributions TVPsales (Figure 1a-2). In addition, investment in 3,000other media channels appeared to continue CPRto drive sales in a fairly constant manner. 2,500By contrast, the TVP modeling approachreveals that Circulars helped boost overall 2,000sales very significantly, and that investmentin other media channels added to the 1,500spike in sales (Figure 1b-2). With a focuson granularity and being adaptive to the 1,000movement of local sales, the TVP modelgives the CMO at SuperiorBuy precise results.Furthermore, since the TVP model analyzes 500available data and also identifies gaps inthat data, it mirrors the real situation.The added value offered by TVP modeling over 8 16 24 32 40 48 56the CPR technique results from the fact that Investment (1000’s)the projection of weekly effectiveness ontoannual sales is closer to the long term averageeffectiveness (Figure 2).
