>There are three VEE issues for clarification - it would be helpful if we
could
>discuss them as part of the MUG conference call.  Maybe we could discuss
VEE at
>a set time during the call, to make it easier for the VEE "specialists" from
>the UDCs to participate.  I can forward your notice to my "VEE" list,
which is
>essentially the PSWG plus people with special interests in VEE who aren't on
>the PSWG exploder.

>Valerie Nibler raised the first two issues, and they*,ve been discussed via
>email.  There seems to be consensus on one, and the other is still open.  The
>third is a new one from our developers.
>
>1.  Point of clarification on estimating holidays.  It is my understanding
that
>you should look for holidays in the current and historical periods, and if
you
>do not find three holidays, you should look for as many additional Sundays as
>required to supplement the holidays.  Average the holidays and the Sundays (a
>total of three days) to create the average profile.   A contrasting
>interpretation is:  look for holidays first, if you find only one, use
that as
>the "average", but if you don't find any, then look for Sundays.
>
>Proposed answer:
>I think you should always try for three days.  This may end up being a
>combination of holidays and Sundays, and current period and historical. I
think
>the priority should be:
>a.  Holidays in current period
>b.  Holidays in historical data
>c.  Sundays in current period
>d.  Sundays in historical data
>
>If you can't find three holidays or Sundays after all this, then you would
back
>off to two days or one day, depending on what you can find.
>
>For example, if the current billing period had no holidays, and historical
data
>had one holiday - use the holiday from historical data, and the two Sundays
>from the current billing period that are closest chronologically to the day
>needing estimation.  (Assumes all the reference days are "good" data.)
>
>
>2. Regarding the statement:  "Intervals containing a power failure cannot be
>used as end points for interpolation."  What intervals should be used as the
>first and second points for interpolation in the case where there is a power
>failure adjacent to the period needing estimation?
>
>There are two "flavors" of answers at this point.  One proposal is to delete
>the sentence from the VEE rules, such that a if an interval with a power
>failure is "next" to a section requiring interpolation, the interval with a
>power failure would be used as an end point.  The other proposal is to use
the
>closest "good" interval as an end point, leaving the intervals with power
>failure alone.  Valerie had worked up some examples that I can't find
right now.
>
>3.  When prorating data, what do you do if one of the intervals in the
section
>being prorated is "bad" - for example, has a pulse overflow?
>
>Proposed answer:  Prorate the intervals except for intervals with other error
>conditions (like pulse overflow).  Then estimate those intervals using normal
>estimation rules.
