Abstract : Ionosonde data characteristics (critical frequencies) change as the distance between two stations is varied from 0-500km. Two statistical models, namely, the Paired Difference model, and the Paired Comparison model, were used to analyze simultaneous vertical incidence (one station) and oblique incidence (two station) data. The analysis was performed with data taken over a 60km path between Fort Monmouth, New Jersey and Fort Dix, New Jersey as preliminary to subsequent testing of various path lengths up to 500km. The analysis was performed with two objectives in mind: (a) To determine whether or not vertical incidence data and oblique incidence data are sufficiently good estimators of each other over a short distance. (b) To determine confidence intervals as a means to compare the two models, and to show a gain of information resulting from the paired difference model. A decision theoretic approach is applied to the two statistical models to attain the objectives. (Author)
