KE Wenqi · 2002
Objective To resolve the problem of orthogonal program design under certain specific test condition in environmental medical study. Methods Using orthogonal program L 8(2 7), 3-factor 2-level test of the combined effect of magnetic field, noise and temperature were carried out. At the same time, Visual Basic language was used in the program to accomplish the functions of data input, orthogonal calculation and variance analysis. Results The design of this program was fine with good man-machine interface, intuitional data display and high precision results. It was quite convenient to operate and increased computing effeciency greatly. Conclusions The application of this test program has proved that it is feasible and effective for resolve certain specific statistic problems.
