Changes in the total electron content in the Earth's upper atmosphere distort the path of GPS signals, causing positions uncertainty in location determinations. Let's say that you have developed a model for predicting the location position deviation near the Ann Arbor municipal airport, and you test it during 6 hours of a geomagnetic storm event, getting these values: Observed position deviation Predicted position deviation (meters) (meters) 15 5 25 25 40 30 45 35 35 45 20 25 Calculate the sample standard deviations of each number set, then find the mean absolute error, mean error, precision difference (Po), and prediction efficiency. How would you describe the predictive capability of the model? You can use a calculator or computer, but show your equations used for each calculation and explain your answer. Expectation: several calculations and a 3-5 sentence paragraph
