Abstract

The invention relates to an improved method for constructing economic indexes on basis of a principal component and a K-L information amount method. The method comprises the following steps of: determining a data item associated with an initial trend; determining at least two data parameters according to the data item and determining a weight value for each data parameter in the at least two data parameters; calculating at least one initial trend point according to each data parameter in the at least two data parameters and the corresponding weight value so as to form the initial trend; fitting the initial trend to generate a time sequence chart of the initial trend; determining at least two consistency parameters for constructing a consistency trend according to the time sequence chart of the initial trend, and determining a weight value of each consistency parameter in the at least two consistency parameters; calculating at least one consistency trend point according to each consistency parameter in the at least two consistency parameters and the weight value so as to form a consistency trend; and fitting the consistency trend to generate a time sequence chart of the consistency trend.

Description

technical field [0001] The present invention relates to the field of information processing, and more specifically relates to a method and equipment for data processing based on the K-L entropy method. Background technique [0002] Currently, economic development always presents cyclical expansions and contractions, as well as cyclical booms and busts. Usually, in different stages of the economic cycle, different industries show different vitality. This pattern is called the business cycle. Economists use the prosperity index to reflect whether the economy is prosperous, and divide the economic cycle through the prosperity index, so as to understand the economic development status of the country and industry, and guide people to carry out economic activities. Although the country has promulgated the prosperity index, economists, statisticians and related professionals usually construct the prosperity index based on the data, so as to understand the state of the country's e...
