Linear Algebra - Least Squares Approximation - 03 - Fitting data to a straight curve Part 1

Показать описание
The least squares approximation theorem is used to fit data to a straight line in a general setting. Note: the column space of A is 2-dimensional provided there are at least two different values for the x's (this is mentioned in more detail in the next video).

These videos were created during the 2019 Spring semester at the UConn CETL Lightboard Room.
