Science and technology service industry development level prediction method based on multiple linear regression

Abstract

The invention discloses a science and technology service industry development level prediction method based on multiple linear regression. The method comprises the following steps that: collecting andcarrying out statistics on science and technology service industry statistical indexes in an existing document, utilizing a frequency analysis method to select a required high-frequency index as thescience and technology service industry statistical index of the method, and establishing a corresponding index system; selecting an index to be predicted from indexes which reflect a science and technology service industry output level as a dependent variable, taking rest indexes as independent variables, and constructing a science and technology service industry index sample matrix; calculatingthe relevant coefficient matrix of the science and technology service industry index sample matrix; on the basis of a step-by-step multiple linear regression algorithm, adopting a proper criterion toselect independent variables as few as possible, and establishing a science and technology service industry development level prediction model; and predicting the selected dependent variable. By use of the method, the independent variable index which affects science and technology service industry development can be dynamically screened, so that the selected index can more accurately predict the dependent variable development, and the development of the science and technology service industry is accelerated.
