### Linear Models and Least Squares

Given a vector of inputs $X^T=(X_1, X_2, \ldots, X_p)$, we predict output $Y$ via the model
$$\hat{Y} = \hat{\beta}_0 + \sum_{j=1}^p X_j \hat{\beta}_j$$
The term $\hat{\beta}_0$ is the intercept, also known as the *bias* in machine learning. Often it is convenient to include the constant variable 1 in $X$, include $\hat{\beta_0}$ in the vector of coefficients $\hat{\beta}$, and then write the linear model in vector form as an inner product
$$\hat{Y} = X^T \hat{\beta}$$
where $X^T$ denotes vector or matrix transpose ($X$ being a column vector). Here we are modeling a single output, so $\hat{Y}$ is a scalar; in general $\hat{Y}$ can be a $K$-vector, in which case $\beta$ would be a $p \times K$ matrix of coefficients. In the $(p+1)$-dimensional input-output space, $(X, \hat{Y})$ represents a hyperplane. If the constant is included in $X$, then the hyperplane includes the origin and is a subspace; if not; it is an affine set cutting the $Y$-axis at the point $(0, \hat{\beta}_0)$. From now on we assume that the intercept is included in $\hat{\beta}$.

This line should be setting title_plaintext like CodeBlock does, instead of title. That should fix it

@Cobertos Thanks. I get it works.

Upstream tag for the inline equation issue. Open to ideas to fix the newline thing, can’t think of an easy way to integrate that
