Spline Regression of Multi-gas Sensors

Regressive analysis is a research of the dependent relations for a certain variable versus other related variables.It can establish the regressive model of the variables with the observation data to forecast and control.At present,regressive analysis has been widely used in various fields such as engineering,economics,biology,medicine,etc.In this paper the spline regressive analysis is used for the information processing of multi-gases sensor signals with the electronic nose system.The authors have established a spline regressive model of the freshness degree of beef based on the beef sample,and have done regressive analysis to the model,which has given the forecast value and the estimative interval of the degree of the freshness of the beef.The results of research show that spline regressive analysis can be used for the information processing of examining the degree of the freshness of the beef with the electronic nose system.
