after i studied the previous involved reserches in order to find the factor that are expected affecting airfares
i found that the airfare is a dependent variable that is the average daily net airfare in any route from all airlines
the related factors can be classified into three groups consist of
the factor group of airlines and services such as distance, number of passengers, flight frequency, advanced booking days, and the presence of airlines
the factor group of airports such as hub airport and multiple airport
the factor group of other environmental factors such as population and per capita income
when the data were collected both the airfare and the factors that is expected affecting airfare and these data were studied the relationship between the airfare and other factos that they have the correlation or not and how
then the data will be analyzed statistically using LIMDEP and Weka with odinary least square method and artificial neural network method, and comparing the results between the two method
the result of linear regression model, both R2 and error, are better than using Neural Network to analyze the data or not
the results showed Neural Network method fits to the nonlinear data distribution more than ordinary Least square method that fits to the linear data distrid=bution
the result can use to explain the airfare in domestic routes, where has the presence of low cost carriers, by looking at R2 and error
the best econometric model has to have the highest R2 and the lowest error
