Manipulating list in order to interpolate

[RPL Calcs]

@ Paste in the HPUserEdit and send to emulator
@ "sigma" is the greek letter sigma (somatory); caracter number 133.

[@ A F(A) B F(B)
[ 1 03.3 10 05.1 ]
[ 3 09.2 20 10.2 ]
[ 5 15.1 30 15.3 ]
[ 7 21.2 40 20.1 ]
]
'sigmaDAT' STO
@ sigmaDAT is the variable that contains the current statistical matrix.

{
3. @ column number specifying the independent-variable: "B"
4. @ column number specifying the dependent-variable: "F(B)"
0. @ intercept
0. @ slope
LINFIT @ regression model
}
'sigmaPAR' STO

@ sigmaPAR is the variable that contains the current statistical parameter list.

LR @ Linear Regression command

@ You'll get in the stack:
@ Level 2: Intercept: .15
@ Level 1: Slope: .501

@ 'F(B)=0.15+0.501*B'

@ NOTE:
@ use real numbers in sigmaPAR, not integers. That is:
@ use { 3. 4. 0. 0. LINFIT } and not { 3 4 0 0 LINFIT }.
