LinearReg
t
Test
treats paired-variable data sets as (
x
,
y
) pairs, and uses the method of
least squares to determine the most appropriate
a
,
b
coefficients of the data for the
regression formula
y
=
a
+
bx
. It also determines the correlation coefficient and
t
value, and
calculates the extent of the relationship between
x
and
y
.
