Evaluating relatively stable points by dividing-into-group regression based on dummy variables;

The daily power consumption was sectionized according to its characteristics of value changing with time and temperature and corresponding dummy variables were imported.

The intercept and slope of dummy variable model do not remain constant ,but the variant of parameter is discrete but not continuous.

Application of dummy variables in electric consumption forecasting;

The Application of Dummy Variables to the Linear Regression Model;

By the use of dummy variables,a practical solution to the lack of fitting of regression is given in this essay.

In the regression analysis,classification variables must be converted to virtual variables.

This paper introduces the basic principle of a forecast model of the virtual variables,and illustrates the process of selecting the model variables.

Emulate teaching based on virtual model of problem——A discussion of teaching method for principles & peripheral technology of micro-computer;

For the key question of the virtual model replace solid model,this paper discusses method of measurement of virtual model based on VRML and key technology for realization.

Exploration of mechanical drawing teaching dummy model bank

On constructing web based dummy model bank by applying vrml technology

By analyzing defects of traditional material object models and advantages of setting up dummy models,the author puts forward that it is necessary to establish and apply dummy test bank to assist teaching of Machinery Drawing based on the three-dimensional CAD software.
