This paper presents an alternative VMT estimation approach that incorporates both traffic counts and link attributes through an exponential regression model in estimating 1ink volumes and VMTs,which are then further disaggregated over the speed and time domains.

The theories of three regression analysis methods were illustrated, which are simple linear regression, exponential regression and weighted exponential regression.

This thesis gave the forecast models of patients survivor life based on learning from fuzzy examples and exponential regression,and got the joint forecast model through optimizing the two kinds of models.

Comparative studies on calculations of index regression and linear regression in determination of water iodine.;

In order to get more reasonable and accurate forecasting values of service life about electronic parts of vehicular electronic equipments,a combined forecasting model combining index regression and gray forecasting was proposed based on the life data of electronic parts of vehicular electronic equipments and some new forecasting techniques.

The trends of spatial variability of soil salinity were similar to each other by three methods,but the spatial distributions of soil salinity by index regression and regression-Kriging were more specific and thorough than that by Kriging interpolation.

It was concluded that the rebound index,coefficient of compressibility and pre-consolid.
