You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: VBA_spm_sdcm_estimate.m
    path of file: ./repos/VBA-toolbox/thrid-party/spm
    
    the code of the file until where you have to start completion: function [DCM] = VBA_spm_sdcm_estimate(P,stochastic,augment,DisplayWin,confounds)
% Estimate parameters of a stochastic DCM for fMRI data
% FORMAT [DCM] = spm_sdcm_estimate(DCM,stochastic,augment)
%
% DCM           - the DCM or its filename

    
function [DCM] = VBA_spm_sdcm_estimate(P,stochastic,augment,DisplayWin,confounds)
% Estimate parameters of a stochastic DCM for fMRI data
% FORMAT [DCM] = spm_sdcm_estimate(DCM,stochastic,augment)
%
% DCM           - the DCM or its filename
% stochastic    - flag for s/d DCM
% augment       - structure for input basis function set (see dcm2vba.m)
% DisplayWin    - flag for inversion report window
% confounds     - onfounds structure
