In this paper,cost prediction of developing a military uninhabited air vehicle( UAV) is addressed with the fact that the sample data are scarce. To overcome the difficulty resulting from the scarce sample data,Gram-Schmidt regression method is utilized to extract the key parameters. Based on the results obtained by Gram-Schmidt regression,the model and algorithm for predicting military UAV development cost are presented. By exploiting the limited sample data,an instantiated prediction model is built and tested. The proposed method is compared with Sequential Multivariable Regression,Artificial Neural Network,and Partial Least Squares. Results demonstrate the practicability and superiority of applying Gram-Schmidt regression method to the prediction of developing military UAV cost.
