A method and apparatus for generating a risk assessment scale

Abstract

The embodiment of the invention provides a method and a device for generating a risk assessment scale. The method comprises the following steps: a risk assessment database is established according tothe basic information of the risk assessment; Interpolating missing values of residual variables; The residual variable is a variable whose data missing rate in the risk assessment database is less than or equal to a preset missing rate threshold; Screening residual variables after interpolation of missing values to obtain key variables for risk assessment; The key variables are verified, and a risk assessment scale is generated according to the verification result. The apparatus performs the method described above. The method and the device for generating the risk assessment scale provided bythe embodiment of the invention can generate the risk assessment scale efficiently and accurately by interpolating the missing value of the variable which is smaller than or equal to the preset missing rate threshold value, screening the remaining variable to obtain the key variable, verifying the key variable, and generating the risk assessment scale according to the verification result.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and in particular to a method and device for generating a risk assessment scale. Background technique [0002] The risk assessment scale is a measurement tool used to quantify risks. In the process of risk assessment, it is necessary to observe all aspects of individuals or groups, and then evaluate and explain the observation results in a quantitative way. The comprehensive score of the scale represents Individual or group risk level. [0003] The construction process of the existing risk assessment scale is roughly as follows: consulting literature, consulting experts, determining risk factors, revising the scale, and pre-test investigation (reliability test, validity test, consistency test, sensitivity analysis, specificity analysis, etc.) , Expert evaluation, repeated improvement and revision of the scale. The above process requires a lot of manpower, mater...
