The following shows the meaning of each item in the case of list data specifica-
tion.
β & ρ ............... p-value test conditions (“G 0” specifies two-tail test, “< 0”
specifies lower one-tail test, “> 0” specifies upper one-tail
test.)
XList ............... list for x-axis data
YList ............... list for y-axis data
Freq ................ frequency
Execute .......... executes a calculation
Example To perform a LinearReg t Test when two lists of data are
input
For this example, we will perform a LinearReg t Test for x-axis
data {0.5, 1.2, 2.4, 4, 5.2} and y-axis data {–2.1, 0.3, 1.5, 5, 2.4}.
