About Revolution Analytics

Revolution Analytics is the leading commercial provider of software and services based on the open source R project for statistical computing. The company brings high performance, productivity and enterprise readiness to R, the most powerful statistics language
in the world. The company's flagship Revolution R Enterprise product is designed to meet the production needs of large organizations in industries such as finance, life sciences, retail, manufacturing and media. Used by over two million analysts in academia
and at cutting-edge companies such as Google, Bank of America and Acxiom, R has emerged as the standard of innovation in statistical analysis. Revolution Analytics is committed to fostering the continued growth of the R community through sponsorship of the
Inside-R.org community site, funding worldwide R user groups and offering free licenses of Revolution R Enterprise to everyone in academia.

Revolution R Enterprise 6.1 includes the following new capabilities:

Big data decision trees. The new "rxDTree" function is a powerful tool for fitting classification and regression trees, which are among the most frequently used algorithms for data analysis and data mining. The implementation provided in Revolution
Analytics' RevoScaleR package is parallelized, scalable, distributable and designed with big data in mind. Revolution R Enterprise continues to offer a wide range of other big-data analysis algorithms, including summary statistics, crosstabs, regression, generalized
linear models and K-means clustering.

New ability to analyze data from Hadoop Distributed File System (HDFS). With more and more data stored in Hadoop, this new option lets data scientists read data from HDFS and apply big-data statistical models from Revolution R Enterprise.

Improved performance for 'Big Data' files. RevoScaleR's 'XDF' file format provides fast access to big data. With new compression technology the size of XDF files can be reduced, allowing for higher-performance analytics throughput and faster
transfers into clusters or cloud processing systems.

Improved Linux installer. The installation process on Linux servers has been streamlined to meet stringent IT requirements, especially for non-root installs.

SiteMinder single-sign for applications: Authorized users of applications built on Revolution R Enterprise deployed via the RevoDeployR Web Services API may authenticate using CA SiteMinder(r).

Customer Churn Prediction and Prevention

What is Customer Churn?

Customer churn refers to when a customer (player, subscriber, user, etc.) ceases his or her relationship with a company. Online businesses typically treat a customer as churned once a particular amount of time has elapsed since the customer’s last interaction
with the site or service. The full cost of customer churn includes both lost revenue and the marketing costs involved with replacing those customers with new ones. Reducing customer churn is a key business goal of every online business.

The Importance of Predicting Customer Churn

The ability to predict that a particular customer is at a high risk of churning, while there is still time to do something about it, represents a huge additional potential revenue source for every online business. Besides the direct loss of revenue that results
from a customer abandoning the business, the costs of initially acquiring that customer may not have already been covered by the customer’s spending to date. (In other words, acquiring that customer may have actually been a losing investment.) Furthermore,
it is always more difficult and expensive to acquire a new customer than it is to retain a current paying customer.

Reducing Customer Churn with Targeted Proactive Retention

In order to succeed at retaining customers who would otherwise abandon the business, marketers and retention experts must be able to (a) predict in advance which customers are going to churn and (b) know which marketing actions will have the greatest retention
impact on each particular customer. Armed with this knowledge, a large proportion of customer churn can be eliminated.

While simple in theory, the realities involved with achieving this “proactive retention” goal are extremely challenging.

The Difficulty of Predicting Churn

Churn prediction modeling techniques attempt to understand the precise customer behaviors and attributes which signal the risk and timing of customer churn. The accuracy of the technique used is obviously critical to the success of any proactive retention efforts.
After all, if the marketer is unaware of a customer about to churn, no action will be taken for that customer. Additionally, special retention-focused offers or incentives may be inadvertently provided to happy, active customers, resulting in reduced revenues
for no good reason.

Unfortunately, most of the churn prediction modeling methods rely on quantifying risk based on static data and metrics, i.e., information about the customer as he or she exists right now.
The most common churn prediction models are based on older statistical and data-mining methods, such as
logistic regression and other binary modeling techniques. These approaches offer some value and
can identify a certain percentage of at-risk customers, but they are relatively inaccurate and end up leaving money on the table.

A Better Means of Predicting Customer Churn

Optimove uses a newer and far more accurate approach to customer churn prediction: at the core of Optimove’s ability to accurately predict which customers
will churn is a unique method of calculating customer
lifetime value (LTV) for each and every customer. The LTV forecasting technology built
into Optimove is based on advanced academic research and was further developed and improved over a number of years by a team of first-rate PhDs and software developers. This method is battle-tested and proven as an accurate and effective approach in a wide
range of industries and customer scenarios.

Without revealing too much about the “secret sauce” of Optimove’s customer churn prediction technology,
the approach combines continual dynamic micro-segmentation and
a unique, mathematically-intensive predictive
behavior modeling system. The former intelligently and automatically segments the entire customer base into a hierarchical structure of ever-smaller behavioral-demographic segments. This segmentation is dynamic
and updated continually based on changes in the data. The latter is based on the fact that the behavior patterns of individual customers frequently change over time. In other words, the “segment route history” of each customer is an extremely important factor
determining when and why the customer may churn.

By merging the most exacting micro-segmentation available anywhere with a deep understanding of how customers move from one micro-segment to another over time – including the ability to predict those moves before they occur – an unprecedented degree of accuracy
in customer churn prediction is attainable.

Beyond Preventing Customer Churn: Preventing Customer Value Attrition

Optimove goes beyond simply predicting which customers will abandon the business by providing early warnings regarding customers
whose lifetime value prediction has declined substantially
during the recent period, even though they are still active and may not abandon the business entirely in the near future.

Optimove’s ability to identify customers which fall into this “decliner” category helps marketers increase revenues from existing customers, while simultaneously reducing the number of customers who may fall into the risk-of-churn category.

Now What? Targeted Proactive Retention

Predicting customer churn is important only to the extent that effective action can be taken to retain the customer before it is too late. A central – and unique – aspect of Optimove is the software’s combination of cutting-edge churn prediction capabilities
and a marketing
action optimization engine.

Once those customers at risk of churning have been identified, the marketer has to know exactly what marketing action to run on each individual customer to maximize the chances that the customer will remain a customer. Since different customers exhibit different
behaviors and preferences, and since different customers churn for different reasons, it is critical to practice “targeted proactive retention.” This means knowing in advance which marketing action will be the most effective for each and every customer.

Conclusion

Optimove’s proactive retention approach is based on combining customer churn prediction and marketing
action optimization. Optimove thus goes beyond “actionable customer analytics” to automatically determine exactly what marketing action should be run for each at-risk customer to achieve the maximum degree of retention possible.
