A Multivariate Linear Regression Algorithm for Cost Analysis

Abstract

The invention discloses a multivariate linear regression algorithm applied to cost analysis, belonging to the technical field of cost analysis, comprising the following steps: establishing a database,subdividing, sorting and classifying the cost of raw materials, electricity and gas, consumption of office supplies, wages of workers, cost of fixed assets consumption, etc.; The data in the databaseare substituted into the multiple linear regression equation, and the basis of data analysis is established. Establish a description of data sources, both external and internal; Through the model calculation and analysis process and model results, the model results include observation value, index value, prediction value, residual and standard residual; The method includes regression statistics,variance analysis and regression parameter table. The invention uses multiple linear regression as an analysis tool to study the relationship between each main cost and the total cost, and reasonablyanalyze and predict the total cost according to the variation trend between the consumption amount of each unit cost and the total cost.

Description

technical field [0001] The invention relates to a multiple linear regression algorithm, in particular to a multiple linear regression algorithm applied to cost analysis, and belongs to the technical field of cost analysis. Background technique [0002] The production link of production-oriented industries is a closed production process with complex processes. It is difficult for tax officials to accurately grasp the production and operation conditions of this industry. [0003] Moreover, products in this industry have a wide range of applications, and raw materials and energy technologies have a greater impact on prices, making it difficult for tax officials to accurately grasp price changes. [0004] In data statistics and analysis, the method of linear regression is often used. Linear regression is a statistical method that uses regression analysis in mathematical statistics to determine the quantitative relationship between two or more variables that depend on each other....
