The fits are limited to standard polynomial bases with minor modification options. 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 statistics and econometrics, particularly in regression analysis, a dummy variable is one that takes only the value 0 or 1 to indicate the absence or presence of some categorical effect that may be expected to shift the outcome. However, multivariate linear regression differs from separately solving individual regression problems because statistical inference procedures account for correlations between the multiple response variables (e.g. Maybe you forgot to add a column in $K$ consisting of only ones as entries. When Pierre puts his cakes in the shop window for sale, he knows he must mark up the cost per cake starting at $1.
