=General= ==What does predictive analytics mean?== {| |- |[[Image:iterating/predictive_analytics.JPG]] |Branch of business intelligence category, predictive analytics uses data mining and statistics to make predictions on future happenings. The predictions tell you what are the odds that a certain event will be taking place or not, under what circumstances, or following trends |} Usually, software tools involve rigorous data analysis to find patterns in historical and transactional information that can help them identify risks or opportunities. They find relationships in the factors that are assessed to guide decision made by a company management by giving a certain set of condition a "predictor". The predictor is a variable that can be assigned to a individual or any other entity to identify its risk or potential and predict its future behavior. In financial systems, credit scoring is used to asses a persons probability of paying in time future credit. The predictors in this case are the individual credit history, income, family members, loan applications and so on. Another popular field where predictive analytics are used is insurance companies. They take into consideration age, gender, driving record before issuing a policy ===Current use of predictive analysis=== The variety of applications where prediction analysis can be applied is endless. In the enterprise world, the success rate of prediction analytical tools is mostly notable in the CRM area but there are also some other fields that are worth mentioned ====Customer Relationship Management==== If you wonder if your marketing campaigns can be improved with a software tool you may find out that prediction analytics can do much more. Many predictive analytics techniques are applied to customer data to pursue CRM objectives, [http://www.iterating.com/productclasses/Customer-Relationship-Management--CRM- CRM] being the most frequent commercial application of this type of business intelligence tools {| |- |[[Image:iterating/people_pie.JPG]] |The central piece, the predictor, in the CRM can be the recency (time since the customer last purchased something), customers time online on your website, monthly usage and so on. The purpose of predictive analytics is to combine this predictors for smarter rankings. The best combination is not easy to find, and that's where predictive analytical tools come in handy to develop the predictive model from the customer data that increases your revenues the most |} The predictive analytics tools build the optimal model automatically, but the overall process to mange and integrate this software is not automatic - you do need the marketing expertise.

Predictive analytics understands the amount of variability and tailors the marketing strategy for better results. For that it take into consideration customer data like past purchasing history, past response rates, demographic etc *'''Customer retention''' To maximize consumer satisfaction in a very competitive market, the likelihood of a customer loss can be predicted and prevented *'''Cross-sell''' For efficient cross selling predictors like spending, usage and history are analyzed *'''New markets''' Using business intelligence modeling, new business models can be design to enter new markets *'''Price estimation''' Agent-based models can find the right parameters for business models (membership fees, , annual fees, emergency fees) ====Human resources==== Tracking employees performance is perhaps the most critical part of Business Performance Management. Predictive analytics provide the tools to better identify the sources of inefficiency and plan corrective actions. Predictive Analytics can also be used for HR planning, helping managers anticipate which skills will be required in the future and in what quantity, with implications on hiring strategy as well as internal mobility. ====Warehouse management==== Portfolio, product or economy level prediction can be made with analytics methods. Distribution of products can be optimized by predicting store level demand for better management of inventories . Adoption of new products can be also accelerated using agent-based models on existing research data ====Financial services==== Scoring models process a customer’s credit history, loan application, customer data, etc., in order to rank-order individuals by their likelihood of making future credit payments on time *'''Underwriting''' A financial company needs to assess a borrower’s potential and ability to pay before granting a loan. Predictive analytics can underwrite these quantities to better predict the chances of on time payment, bankruptcy and so on *'''New services''' The reaction and the likelihood of a customer adoption to a new fee/new service can be predicted. Proper predictive analytics can answer questions like: will the customers use the service, will they refuse to pay for it, will they stop using all your services? *'''Collection analytics''' The cost of collection process can be reduced with the right resource allocation ====Insurance==== Insurance carriers face many challenges in the areas of operational risk, market risk, customer profitability, fraud and ratemaking Predictive analytic tools can empower the insurance industry’s marketing, sales and risk management departments to create revenue opportunities, and reduce risks of loss, at every stage of the customer credit lifecycle, through cost effectively integrate predictive capabilities with their underwriting and pricing engines, to provide comprehensive analysis and surveillance capabilities of their claims systems for retrospective and prospective fraud and abuse detection Fraud is an important loss source within online business especially but False insurance claims, fraudulent transactions, inaccurate applications can be reduced with the means of predictive tools ====Telecommunications==== In telecommunications, predictive analytical models can design network creation and routing policies for distributed data storage. They can simulate network traffic, analyze system under many scenarios and predict its behavior ====Travel==== Efficiency in airport can be predicted with just one variable change, also flight tickets prices can be foreseen. If you want to know if you should wait another day before you fly somewhere as the prices can be much lower, check [http://www.farecast.com Farecast] out -an online services that uses predictive analytics to show you best prices available in the future Scientists focus on predictive analytics for space travel as data mining and probabilistic risk assessment will help improve safety. For instance one engineer using a BI tools can now identify problems in the aircraft structure in three to four hours, where it once took eight engineers six weeks ====Healthcare==== In the healthcare industry, predictive analysis can be applied in many ways. One of the most popular is the health insurance enrollment, where customers are overwhelmed by number of choices. In such a high competitive environment, models can be applied to increase prediction accuracy for health plan registering. Also, for a health insurance provider, predictive analytics can analyze a few years of past medical claims data, as well as lab, pharmacy and other records where available, to predict how expensive an enrollee is likely to be in the future ====Pharmaceuticals==== Pharmaceutical companies are the largest customers of predictive analytics and data mining in general and there are many ways in which they use the BI tools: *Drugs Adoption -The[http://en.wikipedia.org/wiki/Net_present_value NPV] of early-stage compound can be evaluated under wide range of possible scenarios: competitive, regulatory, marketing, market adoption.
