pspm_sf_theta.m

function [theta, sr] = pspm_sf_theta
% ● Description
%   pspm_sf_theta returns parameter values for skin conductance response
%   function  f_SF
% ● Format
%   [theta, sr] = pspm_sf_theta
% ● Developer's Notes
%   Estimated on 29-Jul-2009
% ● Outputs
%    theta: a vector as [theta1, theta2, theta3, theta4, theta5]
%   theta1: ODE parameter
%   theta2: ODE parameter
%   theta3: ODE parameter
%   theta4: delay parameter, should be the same as for aSCR model as there is
%           no explicit knowledge of SN bursts so it cannot be empirically
%           determined this was corrected on 12.05.2014
%   theta5: scaling parameter in log space, was slightly adapted on
%           12.05.2014 such that an input with unit amplitude elicits a
%           response with exactly unit amplitude, see pspm_f_amplitude_check.m
%       sf: sampling frequency
% ● History
%   Introduced In PsPM 3.0
