Checking if two points agree or disagree in data

desireatem — Thu, 23 Nov 2023 15:15:56 GMT

Hello, is there any procedure to check if two points in a data agree or disagree as below:

If in a regression line between b and c, the points are within .95CI then they agree, otherwise they disagree.

In a simple linear regression between b and c, not all data points will fall within two standards of the line. The points that are within two standard deviation agree, while those outside, disagree.

This is the DATA:

Data A ;

Input b c;

Cards;

4 5

6 7

4 4

10 2

9 1

4 5

;

Run;

THIS IS POTENTIAL OUTPUT.

Output D

b c f

4 5 agree

6 7 agree

4 4 agree

10 2 disagree

9 1 disagree

4 5 agree

Please explain the logic by which you can determine "Agree" or "Disagree"

What 95% CI? CI for what statistic? How is it computed? Where is it stored?

If the point in the line between B and C

What point in the line?

If you do a regression using variables b and c, which is the response variable and which is the predictor variable?

THe dependent variable is b and the independent variable is c

The response is b and independent is c.

proc reg data=a;
    model b=c;
    output out=preds ucl=ucl lcl=lcl;
run;
quit;

data want;
    set preds;
    if lcl<=b<=ucl then agree=1;
    else agree=0;
run;

Thank you, this works. It is possible to be able to change the confidence interval to limit 99% CI rather than the default 99% CI?
