    • Systems and methods are provided for evaluating risks associated with alternative strategies for assessing an entity with respect to a predetermined objective. A system includes an action table that contains a plurality of possible actions that can be taken with respect to the predetermined objective for various entity profiles. One or more statistical data stores are configured to contain risk amounts associated with each entity profile, where the one or more statistical data stores are configured to contain inferred percentage distribution of applicants associated with each entity profile. One or more profile identification data stores contain entity identification information for use in determining an action for the entity. One or more improvement data stores provide an indication in the improvement in risk based upon a change in one or more characteristics for an entity profile.
    • 提供了系统和方法,用于评估与根据预定目标评估实体的替代策略相关的风险。 一种系统包括动作表,该动作表包含关于各种实体简档的预定目标可以采取的多个可行动。 一个或多个统计数据存储被配置为包含与每个实体简档相关联的风险量,其中一个或多个统计数据存储被配置为包含与每个实体简档相关联的申请人的推断的百分比分布。 一个或多个简档识别数据存储包含用于确定该实体的动作的实体标识信息。 一个或多个改进数据存储器基于实体简档的一个或多个特性的改变来提供改进风险的指示。

    • Systems and methods are provided for evaluating asset risks using categories of primary loan underwriting factors, which are associated with a pre-selected number of variables. An initial handle-based tree data structure is created in a computer memory based upon the primary loan underwriting factors associated with a loan, where the initial handle-based tree data structure includes a plurality of handle cells that segment a population of loans according to values of the pre-selected variables. The depth of the initial handle-based tree data structure is the number of variables associated with the primary loan underwriting factors, and a branch of the initial handle-based tree data structure is based on a value of one of the pre-selected variables. The initial handle-based tree data structure is modified by combining handle cells which contain least significant splits. A rank ordering of the modified handle-based tree data structure is performed, and the rank ordered handle-based tree data structure is used to segment portfolio data.
    • 提供了系统和方法,用于使用与预先选定数量的变量相关联的主要贷款承保因素的类别来评估资产风险。 基于与贷款相关联的主要贷款承保因素在计算机存储器中创建初始的基于句柄的树数据结构,其中初始基于句柄的树数据结构包括根据值分段贷款人群的多个句柄单元 的预选变量。 初始基于句柄的树数据结构的深度是与主要贷款承保因子相关联的变量的数量,并且初始基于句柄的树数据结构的分支基于预选变量之一的值。 通过组合包含最小分割的句柄单元来修改初始的基于句柄的树数据结构。 执行修改的基于句柄的树数据结构的排序,并且使用基于句柄的树数据结构的等级排序组合数据。
