## OT: Spreadsheet addiction [Software]

❝ ❝ Yep. I wrote a package for this stuff.

❝ Well, you're always several steps ahead of me.

Nope.

*I*started on July 11

^{th}.

❝ My output is for 4 methods only (Z-distribution, homo- and hetero-scedastic and pragmatic) …

Mine only for homo- and heteroscedastic variances (the latter is the package’s default). I think that relying on large sample approximations doesn’t make sense at all. The CI will

*always*be narrower than with the other approaches but why would one go this way? Approximations of degrees of freedom for unequal variances were published in 1946/47 (Satterthwaite, Welch), the

*t*-distribution in 1908 (Gosset a.k.a. Student). Going back more than two than two centuries (Laplace, Poisson, Gauß)? I don’t get it. BTW, I don’t like the pragmatic method.

❝ … since I'm still struggling with Chow and Shao/Liu's methods.

You need the raw data, right?

❝ […] I didn't see the package in your Github page. Any plan to put it there so we can have a peek?

Paid job – chained by a CDA. If we will publish sumfink, sure. Not my decision.

❝ ❝ If you want to reproduce Excel’s wacky “commercial rounding”:

❝ ❝ ...

❝ I doubt I'll very use it but nice to know that it can be done.

I would

*never ever*use it. However, if you want to reproduce sumfink which was rounded in Excel you can only experiment till you get the same in R.

❝ ❝ […] navigate up to my OP and hit to clear the browser’s cache / reload. Is it possible in Excel?

❝

❝ No way. Now you just want to piss off those Excel lovers

Yessir! R is a language and environment for statistical computing and graphics.
