Hi,

I'm trying to do some regression analysis and I do not usderstand the output.

I have run a simpler analysis so I hope someone can help me make sense of the output.

I am trying to get n and e in the following equation

x = n y + e

The data I ran is:

x y

56 89

45 89

12 56

12 263

The code I used is

proc reg data=Try1;

model x= y;

run;

The output I get is

The REG Procedure

Model: MODEL1

Dependent Variable: x x

Number of Observations Read 4

Number of Observations Used 4

Analysis of Variance

Sum of Mean

Source DF Squares Square F Value Pr > F

Model 1 279.11433 279.11433 0.44 0.5747

Error 2 1263.63567 631.81783

Corrected Total 3 1542.75000

Root MSE 25.13599 R-Square 0.1809

Dependent Mean 31.25000 Adj R-Sq -0.2286

Coeff Var 80.43516

Parameter Estimates

Parameter Standard

Variable Label DF Estimate Error t Value Pr > |t|

Intercept Intercept 1 44.02699 22.96735 1.92 0.1953

y y 1 -0.10283 0.15472 -0.66 0.5747

I also plotted the graph in Excel and I got

y = -1.7594x + 179.23

R² = 0.1809

from Excel.

I see the R² value is the same but I don't know which of the output from SAS is the n and e.

I would appreciate any help in deciphering the output.

Thank you.
