I see nothing wrong with the code, and it conforms to the example in the regress documentation.
The only suggestion I have is to use table indexing to replace the initial ‘X’ so —
data = readtable('데이터(최종).xlsx', 'Sheet', 'Sheet5')
% Define the dependent variable
y = data.Arrive;
% Add a column of ones to the independent variables matrix for the intercept, Add a column of ones to the independent variables matrix for the intercept
X = [ones(size(data{:,1})) data{:,3:end}];
% Perform the multiple linear regression
[b, ~, ~, ~, stats] = regress(y, X);
% Display the results
disp('Regression Coefficients:');
disp(b);
disp('R-squared:');
disp(stats(1));
disp('F-statistic:');
disp(stats(2));
disp('p-value:');
disp(stats(3));
disp('Error Variance:');
disp(stats(4));
This is slightly more efficient code, and the result is the same.
