Working Together to

Reduce Transit Losses

Standing Strong

• Provide annually updated analysis of loss trends.

• Use data to drive loss control efforts and employment of resources

• Create awareness of emerging risk/exposures and develop responses

•Create opportunities to share ideas and resources

What is Predictive Modeling?

Historical Actuarial PerspectiveHistorically, actuaries evaluated rates to set pricing and reserves. In a traditional approach they look at characteristic separately

Univariate Analysis

Describes the tradition approach of estimating the impact of one factor without considering others

This is often called a “one-way” analysisContent re-printed with permission from Towers Watson ©2013 all rights reserved

With the advanced in computing technology, actuaries are able to use complex mathematical equations to estimate the impact of all variables simultaneously. This is called..

•GLM or Generalized

Linear Modeling


Benefits of Predictive Modeling• Explore impact of multiple variable simultaneously while taking into account their relationships or correlations

• This allows for more effective pricing in a competitive market

• Better claims handling though identification of claims drivers

• Reduction of risk though probability analysis


How is Predictive Modeling Being Used?

Can Integrate all aspects of your operations and identifies the value of all customers

• Develop Rules• Credit Analysis• Eval Agents• Target Inspections

Competitive Advantage

PriceImprove Retention

& Satisfaction

Claims Advantages•Reduce Claim costs•Improve efficiency in claim handling process – shorten cycle

•More Accurate reserving practices•Better claim Experience leads to higher customer satisfaction


Perform a Claims TriageUse Predictive Modeling to identify complicated claims based on multivariate analysis

• Routed to specialists• Correct Experience for Adjuster• Medial Provider?• Attorney involvement• Return to work• Case management


OTRP Utilized to the study to identify patterns of potential future losses

Predictive Data Analysis allowed us to look at our losses differently. We normally analyze what HAS happened.

This allowed us to see what is likely TO happen.

Predictive Data Analysis

OTRP’s Experience• Re-confirmed what we already knew to be true

• We were able to identify areas of concerns for specific members (not just the pool as a whole)

• Let us think about claim indicators that we might not have otherwise.

FOR OTHERS:

Great management tool for a “hands-off” organization.

Claims management tool for claims intensive organizations.

Creates the possibility to see things in a new and different way
