Hello,
Is there any way to save the output from multiple linear regression into a table? (I don't mean exporting it into excel).
So for example, if I use the patients data set and calculate regression of weight and age on diastolic blood pressure, is there a way to save "Model_1" into a table (a table within matlab)? I realize that the output already looks like a table, but I mean an "actual" table (something like table (a, b, c, ..... ) ).
Many thanks!
P.S.: this is not a homework assignment, I just want to know if it's possible and if so, how to do it :)
load patients Weight Age Diastolic
x = [Weight, Age];
Model_1 = fitlm (x, Diastolic, 'VarNames', {'Weight', 'Age', 'DBP'})
Model_1 =
Linear regression model: DBP ~ 1 + Weight + Age Estimated Coefficients: Estimate SE tStat pValue ________ ________ _______ __________ (Intercept) 72.001 5.1971 13.854 1.0078e-24 Weight 0.056651 0.025884 2.1887 0.03102 Age 0.058378 0.095319 0.61245 0.54167 Number of observations: 100, Error degrees of freedom: 97 Root Mean Squared Error: 6.81 R-squared: 0.0533, Adjusted R-Squared: 0.0337 F-statistic vs. constant model: 2.73, p-value = 0.0704

Save in a cell array. I might not be understanding you completely.
for k=1:10
Model=%your code
c{k}=Model;
end

If you're looking for what I was looking for Model_1.Coefficients contained a table of coefficients
load patients Weight Age Diastolic
x = [Weight, Age];
Model_1 = fitlm (x, Diastolic, 'VarNames', {'Weight', 'Age', 'DBP'})
Model_1 =
Linear regression model: DBP ~ 1 + Weight + Age Estimated Coefficients: Estimate SE tStat pValue ________ ________ _______ __________ (Intercept) 72.001 5.1971 13.854 1.0078e-24 Weight 0.056651 0.025884 2.1887 0.03102 Age 0.058378 0.095319 0.61245 0.54167 Number of observations: 100, Error degrees of freedom: 97 Root Mean Squared Error: 6.81 R-squared: 0.0533, Adjusted R-Squared: 0.0337 F-statistic vs. constant model: 2.73, p-value = 0.0704
Model_1.Coefficients
ans = 3×4 table
