Updated On: 9-Feb-2026

The likelihood that a proposition will be accepted by the customer is stored in the strategy property called_______.

  1. pyPropensity
  2. pyLikelihood
  3. pyProbability
  4. pyBehavior

Answer(s): D

Explanation:

The likelihood that a proposition will be accepted by the customer is stored in the strategy property called pyBehavior. This property is calculated by an adaptive model or a predictive model and reflects the customer's propensity to respond to an offer.

Two results of an adaptive model are

  1. Priority and Propensity
  2. Priority and Evidence
  3. Propensity and Performance
  4. Propensity and Rank

Answer(s): C

Explanation:

Two results of an adaptive model are propensity and performance. Propensity is the probability that the customer will accept or respond to an offer. Performance is a measure of how well the adaptive model predicts customer behavior over time.

Predictive Analytics is a________________

  1. real time predictive dashboard
  2. method of visualizing our data___________________
  3. science concerned with finding repeatable patterns in
  4. query, reporting and a search tool

Answer(s): C

Explanation:

Predictive analytics is a branch of data science that uses statistical techniques and machine learning algorithms to find repeatable patterns in data and make predictions about future outcomes or behaviors.

When compared to a Predictive Model, an Adaptive Model is different as it_____________

  1. can use strategy properties as predictors
  2. considers both symbolic and numeric predictors
  3. learns from both positive and negative outcomes
  4. uses predictor binning

Answer(s): A

Explanation:

An adaptive model is different from a predictive model as it can use strategy properties as predictors. Strategy properties are dynamic values that are calculated or derived during the execution of a decision strategy. They can capture customer context, such as channel, location, time, etc.

What is the difference between predictive and adaptive analytics?

  1. Predictive models can predict a continuous value.
  2. Predictive models predict customer behavior.
  3. Adaptive models use the customer data as predict*
  4. Predictive models have evidence.

Answer(s): C

Explanation:

The difference between predictive and adaptive analytics is that adaptive models use the customer data as predictors, while predictive models use the customer data as outcomes. Adaptive models learn from real-time customer interactions and update their predictions accordingly. Predictive models use historical customer data to train and validate their predictions.
