Problems solved by technology

[0004] However, the above-mentioned Newton iteration method formula involves a derivation part, and the derivation part adopts a derivation formula for derivation. When the number of equations is large, the derivation needs to be performed one by one, and the calculation is more complicated; or, when the equation itself is more complicated, it cannot be obtained. The derivative solution of the formula is difficult to calculate, which seriously affects the numerical estimation of the above index data, thereby seriously affecting the reference factor data of the product

Abstract

The invention discloses a method and related device for determining product reference factor data, and the method comprises the steps: obtaining a known quantity for calculating target index data through the basic information and transaction information of a target product; substituting the known quantity into a calculation function of the target index data to obtain a first estimation value of the target index data; when the output value of the first estimation value substituted into the calculation function does not meet the preset accuracy, obtaining a second estimation value of the target index data through the first estimation value, a Newton iteration method formula and a limit derivation formula until the output value of the second estimation value substituted into the calculation function meets the preset accuracy; the limit derivation formula is used for solving the derivative of the calculation function in the first estimation value; and taking the second estimated value conforming to the preset accuracy as reference factor data of the target product. According to the mode, the speed and the accuracy of numerical value estimation of the index data are improved, so that the speed and the accuracy of determining the reference factor data of the target product are improved.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular, to a method and related apparatus for determining product reference factor data. Background technique [0002] With the expansion of banks' business in the financial market, various financial products have gradually increased. The estimated value of the index data such as the rate of return, duration or convexity of financial products is the core reference factor data for customers to purchase financial products, so the numerical estimation of the above-mentioned index data is particularly critical. [0003] In the related art, in the process of numerical estimation of the above-mentioned index data, the solution of higher-order equations or nonlinear equations is involved; in general, the solution of higher-order equations or nonlinear equations needs to use the Newton iteration method formula. [0004] However, the derivation part is involved in the above-m...
