Question

Quizplus · Accepted Answer

The simple linear regression method is used to obtain a linear trend equation of the form $y t=a+bt$, where $a$ and $b$ are constants. This method involves finding the line of best fit through a set of data points by minimizing the sum of the squares of the vertical distances of the points from the line.
