Risk Management and Risk Predictive Modeling
Risk management can mean many different things. The objectives of risk management is to control factors that may lead to risk being materialized. Risk management is especially important for financial institutions providing loans, mortgages, and finances, and insurance companies providing insurance coverage. For finance and insurance, analyzing past historical data may reveal factors that may constitute risk.
Risk Analysis and Risk Modeling Methods
In this page, the following risk analysis and risk modeling techniques are described. More details are discussed in the subsequent sections;

Risk Factor Relevancy Analysis
How do you know that data you collected are any indicator for predicting risk? In another words, how can you determine that a variable can be a factor for future risk, e.g., credit defaults or insurance claims? The answer is correlation analysis. Correlation is measured between -1 and 1. It indicates the degree of association between two variables. If coefficient is 1, two have perfectly positive correlation. If itís -1, two have perfectly negative correlation. It itís 0, two have no association at all. CMSR correlation link analysis, shown below, is a visualization tool for many-to-many variable correlation analysis. Positive correlations are shown in bright red color, while negative correlations are shown in bight blue color.
Risky Segment Profiling
Profiling risky customer segments is very useful. Customers at risky customer groups may be identified using CMSR hotspot drill-down tools. It can identify risky customer segments through systematic search using artificial intelligence techniques. It can search profiles of risky segment in terms of risk probability, average risk amount, and so on. For example, assume an insurance company keeps records on motor vehicle insurance information in its database containing driver and vehicle information: Gender, age, license experience, education, occupation, drinking, smoking, mobile phone use; vehicle manufacturer, type, model, year make, and so on. The company wishes to know which motor vehicle insurance is at the highest risk groups or highest average insurance payouts. The following is a possible output of hotspot profiling analysis;
Risk Predictive Modeling
Risk modeling refers to the use of predictive modeling techniques to determine the risk level of financial portfolios. Different modeling tasks require different risk modeling techniques. When abundant past historical data is available, predictive modeling techniques, such as neural network and decision tree, can be applied.
