Would you like to show me a manual calculation for this?
Appreciate your helps in advance.
That number looks pretty far off the true value. Have you got a typo in
your example?
You can compute the answer to your question as abs(qt(0.408831/2,
df=1221)), but you'll get 4.117.
D
e detail a manual equation. I really appreciate
it if you may give more detail.
I already gave you the expression: abs(qt(0.408831/2, df=1221)).
For more detail, I suppose you could look at the help page for the qt
function, using help("qt").

Cheers!
On Wed,
for TINV.
Sorry, can't help. I'm not sure I understand what you want, but if it's
a simple formula for quantiles of the t distribution, it doesn't exist.
Duncan Murdoch
Hope solve this problem.
Cheers!

refer to variables like C_ARIMA_Like, which are local to the package
environment of stats. They aren't exported, so your function (which
presumably has a different environment) can't see them.

It's a name, not a description. The result is a named vector.
To get rid of the na

pretty safe to experiment in R. Don't worry, you won't break it.)

Help please
Sounds as though you are having Internet problems. Try the Windows FAQ

Thank you

See the "open.account" example in section 10.7, "Scope", of the
