I have a question about the F test.
In R language, three parameters "two.side", "less" and "greater" can be specified as arguments of var.test (). However, I can not specify a one-sided test like "one.side".
Also, in Microsoft Excel, the F. TEST function was a two-sided test, and the analysis tool's F test was a one-sided test.
I have considered that the one-sided test is mainly used in the F test. Am I wrong?
