    Re: Fix Maximum Probability Positions

    John, you wrote "... don't insert propositions that are absent from the information at hand."
    
    It seems to me you do not heed this principle. In deriving your 'Estimated 
    track made good,' you begin by modifying the information at hand - that from 
    log and compass.
    
    As I wrote before, this is exactly the point at which I, a traditional small-boat navigator,
    part company with you.
    
    I use the data from compass and log to plot a track and a DR. 
    Then I look at the distance between DR and LOP to see if it makes sense in 
    light of the other information I have.
    
    I am using my other information at the end. You, on the other hand, look to be 
    using your other information (information not from log and compass) at the 
    beginning, contrary to the Bayesian principle.

    critical, but it's unknown.  Such a probability distribution implies previous 
    frequency knowledge which is unavailable, and in fact,  unknowable.  This is 
    the major point of Bayesian principles: don't insert propositions that are 
    absent from the information at hand.
