Normal equation for multivariate linear regression

What is the normal equation for multivariate linear regression? In the case of monovariate linear regression, using ordinary least squares, to obtain $\theta^* = \text{argmin}_{\theta} \sum_{i=1}^m (\theta^T X_i - Y_i)^2$ one can use the closed form…

What do you call variable that switches on/off the effect of another?

Suppose we have a model $Y = \beta_1 X_1 + \beta_2 X_1X_2 + \epsilon$ Hence $X_1$ has an effect on $Y$ regardless of the value of $X_2$, but $X_2$'s effect on $Y$ is mediated or enabled by $X_1$. Please fill in the blank: $X_1$ is a ********…

multivariate student-t regression

(1) I want to do a multivariate regression in R (where each output sample is a vector, instead of a number), which I know can be handled using the lm() function; however, the multivariate output data is not necessarily normally distributed, so I'm…
