One potential method we may forecast is through the use of a "trend" in sales history using multiple years of sales data.

If we are asked to calculate this trend through the use of

**Linear Regression calculations**(e.g. X and Y values, slope, etc), I'm curious if there are

any built-in functions and/or Operators that would help in these calculations or would we have to write custom code to do the calculations "long-hand"?

My initial search of the available Mathematical Built-In Functions only finds: Exponential, Random_Num_Generator, Round, and Square_Root.
