Error in t(Y_norm) %*% x : non-conformable arguments

Null is a term used to describe the absence of a value or a lack of content. In programming, null is often used to indicate that a variable or object has not been assigned a value. It can also be used to indicate a lack of data or an undefined state. In databases, null is used to represent missing or unknown data.
