Additions:
[loglik,m,d] = FitCumGauss_MES(p,r,mset,dset,lapserate,guessrate)
By default, a psychometric function ranging from 0% to 100% is used, as
is suitable for discrimination experiments with a standard in the middle
of the possible stimulus parameter range. For other paradigms, such as
detection tasks, one can set the guessrate input to 1/num_alternatives,
e.g. .5 when doing a 2IFC detection task.
Optinally fits with a lapse rate, which defaults to 0. If a lapse rate is
set, the cumulative Gaussian levels off at lapserate/2 and 1-lapserate/2
when the guessrate is 0. If the guessrate is non zero, the cumulative
Gaussian that is fit ranges from guessrate to 1-lapserate
Deletions:
[loglik,m,d] = FitCumGauss_MES(p,r,mset,dset,guessrate)
Optinally fits with a guess rate, default 0. If a guess rate is set, the
cumulative Gaussian levels off at guessrate/2 and 1-guessrate/2.
