The second method deals with strategic optimization techniques and gives another example of the simplex method implemented by the Nelder-Mead algorithm used in the Matlab function try typing 'help regress' at the command line, it will give you the input format. It sounds like you might have a newer version of Matlab that has updated the function and no longer requires as many inputs. 此 matlab 函数 返回向量 b,其中包含向量 y 中的响应对矩阵 x 中的预测变量的多元线性回归的系数估计值。要计算具有常数项(截距)的模型的系数估计值,请在矩阵 x 中包含一个由 1 构成的列。 I have a dataset comprising of 30 independent variables and I tried performing linear regression in MATLAB R2010b using the regress function. I get a warning stating that my matrix X is rank deficient to within machine precision. Now, the coefficients I get after executing this function don't match with the experimental one.

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. In MATLAB, you can find using the mldivide operator as B = X\Y. From the dataset accidents, load accident data in y and state population data in x.
