Q

What are the buillding blocks of Decision Models?
What are the Inputs and Objectives?

A

–>the buillding blocks are market response models

  • Inputs: marketing actions (price, advertising)
  • Response models: linkage from those inputs to the measurable outputs of concern to the firm (customer awareness levels, sales levels)
  • Objectives: measse that the firm uses for monitoring and evaluating those actions

Q

Why do we do variable transformation in Market response models?

A
  • transformations are applied to the predictor variables (also known as independent variables or features) used in the model

–>By transforming the variables, analysts aim to create a better fit between the predictor variables and the response variable, leading to a more accurate and reliable model.

Q

Process (variable) transformation
(Average price, distribution factors, Seasonality)

A

transform independable inputs into usable data

Average price= Base price + discount
–>to better evaluate the impact of promotional discounts and base price elasticity

Distribution: split the width: number of stores, depth: how many products per store

Seasonality: is a periodic repetition or cyclic variation in time series data
Important before quantifying the impact of marketing promotions
–>it is crucial to separate the impact of seasonality to ensure no misguided recommendations

Q

What curve to we use to Model the Saturation Effect on Media promotions?
(Multivariate regression Models)

and why not linear?

A

We use a S-shaped curve to model the saturation effect on Media promotions

Not linear: since the relationship between media adstock and sales is not linear

–>However, a logistic function can map the media impact on sales

Thus we use s-shaped function since, It can reproduce market saturation at some point in time

Q

How can the carryover effect and the decay effect influence the adstock?

Carryover effect and Adstock

A

The carryover effect contributes to the building of Adstock.
- Each exposure to advertising leaves a residual impact on consumer behavior (creating memory or impression)
- these impression accumulate to the Adstock
–>The more frequent and consistent the advertising exposure, the stronger the carryover effect and the higher the Adstock level

23
Q

, What does the term “Rule” mean in Market Basket Analysis?

A

Rule: Incidence across transaction of one set of items as condition of another set of items
–>represents an association or relationship between sets of items in customers’ transactions. These rules are typically in the form of an “if-then” statement

Lift >1 –>items tend to be purchased together
–>Never put both products on sale

27
Q

How to calculate the lift?

A

Lift calculation

likelihood of an event occurring when a specific condition is present (e.g., a customer purchases product A) to the likelihood of the event occurring in general (e.g., a customer purchasing any product)

28
Q

How do Neural networks forecast sales? Compared to multiple regression

A

Neural networks seaches many models to find a relationship with independent variables that best predicts the dependent variables
- they can capture even complex relationships that multiple regression cannot find

  • Important to identify and distinguish the effect for correctly estimate the impact of promotions
34
Q

What are Market Share Models?
what is the difference between single brand models to market share models

A

used to understand how marketing of every brand impact the results in a competitive marketplace

–>Unlinke single-brand sales modles, they also include competition

35
Q

Formula and intution behind Market Share?

A

Market share = k*M (k= proportionality constant; M=Marketing effort)
–>the greater the marketing effort, the greater the market share should be

36
Q

What is Bell, Keeney & Little Market share theorem idea?
(attraction),

A

they argue, that the only determinant of market share is the attraction which consumer feel towards each alternative brand

37
Q

What is Bell, Keeney & Little Market share assumption?
(attraction),

A

attraction of a brand is proportional to is marketing effort and interpret attractions as probabilities

–>Attraction models

38
Q

What is Kotler´s Theorem of Market Share?

A

The theorem says:

That the market share of a brand = to the brand´s share of the total marketing effor

39
Q

What assumption do Market Share attraction Model underline?

A

attraction of a brand depends on its marketing mix

40
Q

How do Market share attration models derive market shares?

A

–>Modelling attractions as probabilities
Brand attractions are determinants of market shares!

–>they interpret market shares as purchase probabilities

41
Q

Strategic PLanning:
What do Market Response Models offer?

A

Superior allocation:
- Identify marketing channels tht max returns
- Compare tradition channels with emerging, cost effective ones

Superior execution:
- propose the right execution levels for highly effective markeitng channels (avoid saturation)
- Investigate successful campaings, their types or quality scores
- compare campaign duration

Simulation & optimization:
- Forecast sales trend as per current marketing mix plan
- Predict sales impact subject to a planned increase/drop in advertising/price
- Create an optimum marketing mix plan to achieve target revenue growth

42
Q

Challenges of Brand & Product Sales Models

A
  • requires leveraging a diverse set of data sources
  • missing measurment standards for external data –>data credibility
  • difficulty of capturing the long-term effects of advertising campaigns as component of base sales
  • ## Making market mix recommendations –>big operational challenge
43
Q

What is Non- transactional data?

A
  • refers to data that is not explicitly tied to individual transactions or purchases.
  • It includes data that describes characteristics, attributes, or preferences of customers, products, or other entities related to the market being analyzed
44
Q

Which curve is used to forecast sales of a new Product and what can they learn from the curve?

A

S-Curves are used to forecast sales of a new product

  • Upper limit of sales
  • Inflection point (Wendepunkt)
  • Future profitability
45
Q

What is the usage of the Pearl curve?

A

Pearl curve is used to model the path of product diffusion by fitting the logistic curve

46
Q

What needs to be down when fitting a Logistic curve with seasonality?

A

the seasonality of sales must be incorporated into the estimation process by

–>multiplying the forecast from the S-curve with the appropriate seasonal index

47
Q

What is the Gompertu Curve?

A

is another function form that is often used to fit an s-curve to data for forecasting sales

48
Q

What is the difference between Neural network and Regression analysis in forecasting sales? (Assumptions, relationships)

A

Observations and Goal is the same

Regression analysis
Assumptions: requires statistical assumptions about the data
Relationships: relationship between IVs and DV needs to be specified

49
Q

For what can we use Moving averages?

A

Used to smooth data and eliminate seasonality

50
Q

What are the terms consiered in Multiplicative Model with Trend and seasonality?

A

Sales t = Base*trend * seasonal index month t

Trend: % monthly increase in the level of airline miles
seasonal index: % by which airlines travel for the month is above or below an average month
–>Multiplicative seasonal indexes must average 1

51
Q

What kind of Model is the Multiplicative Model with Trend and seasonality?

A

It is a non-linear forecasting model because one can raise the trend to a power and multiply it, rather than add terms involving the seasonal indices

52
Q

What are the three terms considered in an additive Model with Trend and Seasonality?

A

Predicted period t sales= Base + Trend*t + Seasonal index month t

Base: best estimate of the level of monthly airline miles at the begining of the observed period (without seasonality)

Trend: Best estimate of monthly rate of increase in airline miles travelled

Seasonal index: each month has seasontial index to reflect –> the seasonal indexes must average to 0.

53
Q

Using Neural networks to forecast sales:
(Observations, Goal, Assumptions, Relationshipps)

A

Observation: each observation contains a value for each dependent and independent variable

Goal: to make accurate predictions for the output or the dependent variable

–>Observation and Goal: same as for regression analysis

Assupmtions: No statistical assumptions about the data needed
Relationships: find patterns by learning from the data

54
Q

Which curve to use in predicting sales?
(Pearl Curve or Gompertz Curve)

A

3If future sales benefit from previous product sales –>Pearl curve

If future sales do not benefit from previous sales –>Gompertz curve
