As for the 'Raw' time series, the results in Table 1 show that FN+WN, FN+WN+RW, PL and FOGM
model account for 51 %, 12 %, 37 %, 0 %; 50 %, 18 %, 32 %, 0.0 % and 50 %, 2 %, 41 %, 6 % for the NEU component respectively.
An unexpected event occurred in 1985 that had important implications for FOGM. Defense Secretary Casper Weinberger made the decision to cancel the Army Air Defense Center's Division Air Defense (DIVAD) anti-helicopter gun system, also known as the Sgt.
Jerry Dooley observed, "It turned out that FOGM was sitting in the wrong place at the wrong time, because he was looking for an example, and there we were, with our estimates showing us way over [budget]" (personal communication, May 3, 2001).
The amplitude and phase were determined by means of the Least Squares Estimation (LSE) with uncertainties calculated with the coloured noise assumption by means of the First Order Gauss Markov Model (FOGM
