 PAL_PFML_GoodnessOfFit     Determine Goodness-of-Fit of psychometric

    function (PF) using method in Wichmann & Hill, 2001, Perception &

    Psychophysics, 63, 1293-1313.

：

 

Output: 

    'Dev': Deviance (transformed likelihood ratio comparing fit of

        psychometric function to fit of saturated model)   ----> Wichmann & Hill, 2001, p.1303 参照

 

    'pDev': proportion of the B Deviance values from simulations that were

        greater than Deviance value of data. The greater the value of pDev,

        the better the fit.
