      XPost: alt.ufo.reports              EXECUTIVE SUMMARY:       - News of a re-connect with Voyager 2 prompted a model to see whether        probe fly-bys of the outer planets is associated with features in        UFO sightings data between (say) 1950 and 2000.       - It seems the best-fit model finds all 4 planets is associated with        features in the sightings data. 2 planets appeared to be associated        with an increase in activity on approach of probe(s) and a decline        after they pass; the other planets are the opposite.       - The fit now explains some of what appeared to be "random walks" in        parts of the UFO sighting data.       - A future model is planned to examine in more detail the "double hit"        from the Voyagers at Jup and Sat that visited months apart in 79 and        then in 80/81.       - It seems everywhere you choose to look there are "signs". Why are        these now-old results not known? Wilful blindness?                      Earth to Voyager 2: After a Year in the Darkness, We Can Talk to You Again        The New York Times, 12 Feb 2021 10:43Z        In the nearly 44 years since NASA launched Voyager 2, the spacecraft has        gone beyond the frontiers of human exploration by visiting Uranus, Neptune        and, ...              It will be 44y in mid Aug.              But it got me to thinking if all (if you mean 2) these probes       converging on Jupiter and Saturn in 79 and 80 might have caused some       kind of reaction if there are any "alien bases" out around there.              So we have to build a mathematical model and see whether the sightings       really seem to be affected by some effect of probes getting closer and       closer and closer and then getting further and further away and then       getting closer and closer and ... well, you get the idea.              So the basic element of this model will look like a_i(t_i-d)^r.       I.e. there is a "target date" (t_i) when a probe was due to run past       one of the outer planets, there is the current date (d). And there       are a couple parameters (a_i, r) that need to be estimated to best-fit       the UFO sightings data.              To start with I'll only include the first dates for each of Jup, Sat,       Ur and Nep and gloss over the fact both Voyager 1 and Voyager 2 passed       by Jup and Sat within months so really those 2 components of the model       should be weighted a bit more heavily than Ur and Nep where only V2       visited. But maybe the fitting procedure will end up making the a_i       for Jup and Sat bigger than for the other 2. Like you, I can hardly       wait to see.              I rigged up a simple fitter/optimizer using a genetic search for the       a_i and r on top of a basic time series regression with the overall       aim to maximize the R2 of the final model.              I also tried the "net present threat" type of function with terms like       a_i(1+r)^(|t_i-d|) but these turned out to be a slightly worse fit       than the first cut (above). If seems Our Friends are not ready to       reveal their time-discount rate to us at this point! :)              After a few sec of chugging on what remains of poor old "baby"       ( |
