Program PARC0H2 [electronic resource] : partial and multiple coherences, transfer functions in the frequency domain / by F.M. Boyce. [Burlington, Ont.] : [National Water Research Institute], 1986. 18, [13] p. NWRI contribution ; # 86-26 Digitized edition from print [produced by Environment and Climate Change Canada]. "It is hypothesized that bottom currents in Lake Erie are driven by three forces, wind stress (through surface pressure gradients), internal pressure gradients (thermocline tilts), and coriolis force. An individual velocity component is thus a function of 5 variables, two components of wind stress, two components of internal pressure gradient, and the other horizontal velocity component. Ordinary coherence functions between the dependent variable and the independent variables, taken one at a time, are not reliable indicators of this functional dependence because of the correlations among the independent variables. From standard references on time-series analysis (Bendat and Piersol, 1971. Random Data: Analysis and Measurement Procedure. Wiley-Interscience. Otnes and Enochson,1972. Digital Time Series Ainalysis. Wiley-Interscience.) and using IMSL and matrix inversion routines, a computer program has been assembled to compute multiple and partial coherences, transfer functions and phase angles, between the dependent (single velocity component) and the independent variables. This report has been written because extensions of this routine may be useful in other, similar applications"--Abstract, p. 2.
