Hi,
I have been unable to find how to go about changing the significance
level
in R for hypothesis testing and regression analysis. R has a default
setting
to alpha=95% (a significance level of 95%), but I want to be able to
decrease or increase this level when necessary. If you could give me
instructions on how to change the significance level in R for
hypothesis
testing and regression analysis I would appreciate it.
The lm() page refers you to the predict.lm() page for confidence
intervals.
