Since 1939,many parameter estimation methods have been proposed,including the probability weighted moment method,the maximum likelihood method,bilinear regression method,correlation coefficient method and Grey estimation method/ The methods mentioned above are disscussed,programs and examples are given.

Optimization of the extraction process of Suchangshi-ZhuyutangⅡ by orthogonal design and linear regression;

Application of a linear regression and iterative-exclusive method in 2D~1H MRS from Astrocytoma;

Application of multiple linear regression technology in hydrological information system;

Through the investigation of amounts and quality of main organic pollutants in the life pollution outlet of Jian Jiang basin, a series of equations were thus established based on the linearity regression analysis.

In this paper,the linearity regression has been used to construct the model based on the data got from questionnaires,drivers static indexes(deepness aesthesia,attention centrality,attention assignment) and steering reaction time of drivers upon the driving stimulator,and also proved to the validity of the model through data check-up.

Through linearity regression to the concentration curve of Fe,it gets rid of the influence of the concentration changing,and it ensures the current research of wear and failure.
