George Huxtable advocates this "simple message": > "Plot a point, at the centre > of the triangle, but be aware that the true position could lie well > outside that triangle." Since this is a somewhat "tendentious" (lovely word, that) argument about statistics, isn't the chance of the "true position" lying within one standard deviation of a position line about 70% ? (Whilst retaining the assumption of a standard distribution of error.) And within two standard deviations about 90% ? What evidence can you present, George, for the "true position" being at all likely to lie "well outside" the triangle - or other shape? Is it not correct that the most likely place to find this "true position" is close to the position line? --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to NavList@fer3.com To unsubscribe, send email to NavList-unsubscribe@fer3.com -~----------~----~----~----~------~----~------~--~---
