Z Points Calculation

21 May 2006 (Updated 23 May 2006)

Returns the Z-points (for use if you don't have Statistics toolbox)

File Information

Description

Returns the Z-points of the points making up a psychophysical curve.

If the values are out of bounds the function returns NaN. If they are 0 or 1 (which would give -Inf and +Inf) the values are rescaled

It doesn't perform miracles, but it helps analyzing psychophysical data (data fitting, d' calculation etc)

MATLAB release

MATLAB 6.0 (R12)
