Calculate starting values for an ARF model
determineStartRect calculates starting values for an ARF model by searching for maxima and minima in the data, and estimating the width of these maxima/minima.
An ARF model object (class
An "options" object (class
determineStartRect determines the maxima and minima of the data and at each maximum/minimum searches in each dimension (x,y,z) the point where the maximum/minimum value is half its original value. This creates a box around the maximum/minimum, which is set to zero, to avoid searching the same area twice. The widths of this box are taken as starting values for the width-parameters.
Returns the ARF "model" object, with the starting values in the
