Commands When Linear Regression Calculation (A+Bx) Is Selected

With linear regression, regression is performed in accordance with the following model equation.

y= A + BX

The following are the commands that appear on the sub- menus that appear when you select (Sum), (Var),  (MinMax), or (Reg) on the STAT menu while linear regression is selected as the statistical calculation type.

x =	∑x			y =	∑y
	---n-----				---n-----
xσn	=	∑(x – x)2		yσn	=		∑( y – y)2
		-------	----n-------------				-----------n-------------

xσn – 1		=	∑(x – x)2	yσn – 1		=	∑( y – y)2
			-------n----–-----1--------				-------n----–-----1--------

	∑y – B • ∑x
A =	--------------------------------
			n
