Embodiment Construction

[0006] A statistical analysis system applying the linear regression method includes: a system for receiving samples; processing samples to an analyzable system; further calculating various parameter systems required by the linear regression model according to the contents of the samples; Linear regression model system; the conditional mean of y for a given value of X is an affine function of X. Less generally, the linear regression model can be a median or some other conditional distribution of y given X The quantiles of are expressed as a linear function of X. Like all forms of regression analysis, linear regression also focuses on the conditional probability distribution of y for a given value of X, thereby enabling analysis. The linear regression model was fitted using a least squares approximation. Linear regression has many practical uses. Divided into the following two categories: If the goal is prediction or mapping, linear regression can be used to fit a predictive mo...

Abstract

The invention discloses a statistical analysis system applying a linear regression method. The statistical analysis system is characterized by comprising a sample receiving system, a system for processing samples to be analyzable, a system for further calculating all parameters needed by a linear regression model according to the content of the samples, and a system for manufacturing the linear regression model according to the calculation result of the step three. The conditional mean of y with a given X value is an affine function, under unusual conditions, the linear regression model can be a linear function representation with a median or other quantiles of conditional distribution of y under the condition of the given X serving as X, and like regression analysis in all forms, the focus of linear regression is put on conditional probability distribution of y with the given X value to achieve analysis. The linear regression model uses least square approximation for fitting. Estimated statistical properties generated by linear regression are easy to determine, and therefore the efficiency of statistical analysis is improved.

Description

technical field [0001] The invention relates to a statistical analysis system applying a linear regression method. Background technique [0002] The statistical analysis of the school is to count, analyze and export the Excel table through the evaluation form after the evaluation, print it into a standard A4 format file, and form various charts. There are no less than 5 types of icons, such as line charts, Column charts, stereo charts, pie charts, radar charts, etc. Then based on human review, intuitive assessment. It is very unfair to do so. If the obtained data is not collated and analyzed, the problems contained in the data will be revealed. Makes the analysis job unfair. Linear regression is a type of regression analysis that models the relationship between one or more independent variables and a dependent variable using the least squares function known as the linear regression equation. Such functions are linear combinations of one or more model parameters called r...
