Hey, I am doing a regression analysis course and i need to find the 95% confidence interval of a given data,

but i can't find the code to compute it anywhere.

Please, share with me your ideas

input team opponents;

You can't do a linear regression on this data.

You need two variables — an independent (or predictor) variable and a dependent (or response) variable.

Your variable TEAM is an identifier and can't be used in a regression equation.

Hey Miller,

I have indeed two variables, one is team and the other one is opponents.( y and x8 in the data below)

and i was able to find beta0 and beta1 .

I know looking for the 95% Confidence interval for the slope .

I cant the code for 95% CI for slope

If you used PROC REG, then you need to add the CLB option into the MODEL statement thusly:

model y=x9/clb;
