Sensitivity in Simple Linear Regression

Hi,

I was asked to do sensitivity analysis for my simple linear regression models but I do not know how.

If I have my simple PROC REG code

```PROC REG data=dataname;
model Y=X;
run;```

and I get my results. Is there anything I need to look at specifically for sensitivity or is there another procedure that would give me the sensitivity?

Would sensitivity just mean the coefficient for the variable ?

That's a reasonable understanding of the meaning of the word "sensitivity", but there are other reasonable meanings, and you need to clarify what is meant by "sensitivity" before actually doing the analysis.

Re: Sensitivity in Simple Linear Regression

Sensitivity and specificity are statistical terms but would not apply to a linear regression with the standard model. Logistic regression would include a sensitivity analysis.

A more detailed description of your problem is required.

Likely not.

Statistical definition

That being said, sensitivity analysis is a different topic which could possibly be what you're looking for here?

Re: Sensitivity in Simple Linear Regression

I'm not trying to argue as I have no idea but I found this on wikipedia:

Regression analysis, in the context of sensitivity analysis, involves fitting a linear regression to the model response and using standardized regression coefficients as direct measures of sensitivity.
