It was also found that Support Vector Regression tends to favour longlived data while standard Matlab regress balance between long lived andshort lived data.

Calculate R squared from a linear regress .

From MATLAB documentation: regress is for multiple linear regression. You just want to find relation between X and Y. For that polyfit command should be enough. I think the column of ones is necessary only when you want to calculate statistics. You will use regress when you want to find out how Z behaves with respect to X and Y. In short, Z=f(X,Y).

Copied verbatim from Matlab documentation: Alternative Functionality regress is useful when you simply need the output arguments of the function and when you want to repeat fitting a model multiple times in a loop.

Linear regression fits a data model that is linear in the model coefficients. The most common type of linear regression is a least-squares fit, which can fit both lines and polynomials, among other linear models. b = regress(y,X) は、行列 X 内の予測子に対するベクトル y 内の応答についての多重線形回帰の係数推定値が格納されているベクトル b を返します。 定数項 (切片) があるモデルの係数推定を計算するには、1 の列を行列 X に含めます。 [b,bint] = regress(y,X) は、係数推定値の 95% 信頼区間が格納されて MS_Regress-Matlab.

b = regress(y,X) returns a vector b of coefficient estimates for a multiple linear regression of the responses in vector y on the predictors in matrix X.To compute coefficient estimates for a model with a constant term (intercept), include a column of ones in the matrix X. [b,bint] = regress(y,X) also returns a matrix bint of 95% confidence intervals for the coefficient estimates. From MATLAB documentation: regress is for multiple linear regression. You just want to find relation between X and Y. For that polyfit command should be enough. I think the column of ones is necessary only when you want to calculate statistics. You will use regress when you want to find out how Z behaves with respect to X and Y. In short, Z=f(X,Y). I am conducting a multiple linear regression analysis with the following regress command: [b,bint,r,rint,stats] = regress(y,X) Where b is the coefficient array.
