I created the following SLR model using:
fit <- lm(WAge ~ HAge, data = couples) # regress wife's age against husband's age summary(fit)
...and it worked just fine.
However, I want to calculate the confidence intervals using
confint(), but instead of the customary:
2.5% 97.5% (intercept) HAge
...it keeps on returning a logical value, in this case [TRUE]. Would anyone happen to know why this is happening? Thank you!!!
