Fitting a psychometric curve using pyTorch Scientific logbook
WebPsychometric curves are typically not step functions. The reason that there is a gradual change in performance is that there are various sources of uncertainty that subjects face when doing the tasks: Noise in the display or stimulus (because it is a physical device) Random number generators in the computer program that creates the display image Webscipy.optimize.curve_fit(f, xdata, ydata, p0=None, sigma=None, absolute_sigma=False, check_finite=True, bounds=(-inf, inf), method=None, jac=None, *, full_output=False, … herren 160 years hs hooded jacke
