does Calc permit regular expressions in the FIND() function?
I think FIND doesn't, SEARCH does

I have been working on adding multiline formulae support
Nice one - this prob comes up in the user forums quite often. One
thing worth testing might be how it works when a user searches
with regex. Can't see why it would be a problem, but looking for
eg newlines is always thorny in Calc.
Hi Eike
Following up here on your response to this issue. Thanks for
looking at it.
Say we have A1:C1 = {7|6|5}
In cell A2 we enter, as an array formula:
=PROB({5;6;7};{0.2;0.3;0.5};A1:C1)
and, correctly, A2:C2 = {0.5|0.3|0.2}.
Now in cell D4 we enter, as a normal (non-array) formula:
I agree, NORMSDIST is OK. But ZTEST doesn't use it, but
calculates all
itself.
It actually does use gauss() - which I assume is at the heart of
NORMSDIST.
GAUSS()=NORMSDIST+0.5 I think.
Wouldn't it be more natural to calculate a real sigma than a
variance?
I mean
sigma =
Moving discussion of this issue here, at Regina's request.
Hi Regina
The function ZTEST should depend on NORMSDIST.
Therefore NORMSDIST has to be controlled and improved first.
I'm afraid I disagree pretty whole heartedly :)
NORMSDIST may or may not be more accurate in Excel, but in Calc
it
I only added the accuracy of the SD-algorithm into the discussion,
because the naive single pass algorithm used inside the ztest routine
may give very wrong results,
I'm sure you are right - but perhaps this should be a separate
issue that can indeed wait for a while?
This separate
Hi Eike
Thanks for the help.
Effectively you're now trying to confuse the interpreter ;-)
No, the cause seems to be that for the case of dimension arguments being
given, internally always a range reference is returned. Didn't verify,
but I think that returning a single reference for the case
