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: ft_statfun_depsamplesregrT.m
    path of file: ./repos/malini/Codes/deconvolution - model/spm8/external/fieldtrip/statfun
    
    the code of the file until where you have to start completion: function [s,cfg] = ft_statfun_depsamplesregrT(cfg, dat, design)

% FT_STATFUN_depsamplesregrT calculates dependent samples regression T-statistic 
% on the biological data in dat (the dependent variable), using the information on 
% the independent variable (iv) in design.
%
% Use this function by calling one of the high-level statistics functions as:
%   [stat] = ft_timelockstatistics(cfg, timelock1, timelock2
    
function by calling one of the high-level statistics functions as:
%   [stat] = ft_timelockstatistics(cfg, timelock1, timelock2, ...)
%   [stat] = ft_freqstatistics(cfg, freq1, freq2, ...)
%   [stat] = ft_sourcestatistics(cfg, source1, source2, ...)
% with the following configuration option:
%   cfg.statistic = 'depsamplesregrT'
% see FT_TIMELOCKSTATISTICS, FT_FREQSTATISTICS or FT_SOURCESTATISTICS for details.
%
% For low-level use, the external interface of this function has to be
%   [s,cfg] = statfun_depsamplesregrT(cfg, dat, design);
% where
%   dat    contains the biological data, Nsamples x Nreplications
%   design contains the independ
