DFLer Rebecca Otto is accusing Auditor Pat Anderson, a Republican, of sloppy

from 2003 to 2004, instead of dividing the difference by the 2003 figure, the
auditor's office divided it by the 2004 figure. Deputy Auditor Tony Sutton
said "The researcher who worked on that report just made a mistake in the
formula in the spreadsheet. He feels bad about it."

Dud spreadsheet threatens case By Leonie Wood November 10, 2005 A
MULTIMILLION-DOLLAR petrol price-fixing case being led by the Australian
Competition and Consumer Commission in the Federal Court has been seriously
jeopardised by admissions from it that one of its investigators made up some
of the evidence. The ACCC is relying on a huge spreadsheet which lists petrol
prices and times of price changes to corroborate oral evidence from witnesses,
including some of the petrol station operators, that Geelong fuel retailers
worked together to push up prices in 1999 and 2000. ACCC's chief investigator
Jane Edwards admitted that "at the risk of fingering one of my staff members",
one of the investigators had cut and pasted slabs of data into the
spreadsheet. Ms Edwards at the time told the court that the investigator was
"very enthusiastic and he thought he had skills that we weren't aware of that
might be of use", so he hurdled the problem that the ACCC lacked information
about price movements on some dates by duplicating data from other dates.

"NEW YORK (Reuters) - The
Business Council, a group of 125 U.S. CEOs, last week said 70 percent of its
members expected flat to 2 percent growth in the U.S. economy next year --
painting a much more bearish outlook than major economists. But on Tuesday, the
group said it had gotten the survey wrong and its members had actually projected
moderate to solid economic growth in 2005, from 2.1 percent to 4.5 percent, and
were 'guardedly optimistic' about the economy's prospects. 'It was a
computational error. The spreadsheet shifted so the wrong numbers appeared in
the wrong columns,' Cassidy said. 'It was just one column on the spreadsheet.'

The stock exchange said Cusack, 47, bought large blocks of Foremost stock in

clients would have the stock placed in their accounts. The lack of
documentation raised the possibility that he could wait to decide how to

Education Networks of America (ENA)
operates the Internet network connecting schools across Tennessee. ENA twice
won multimillion-dollar state contracts with bids that appeared higher than
others. Jacqueline Shrago, who was the Education Department's project manager,
said the ISIS 2000 bid appeared cheaper until costs for all three and a half
years were computed. Looking more closely, it appeared that ISIS had made an
error on a spreadsheet and that the bid actually was higher than ENA's, she
said. 'We asked questions in the protest period, and they would not give an
answer,' Shrago said. She said ISIS never explained, either, to federal
agencies, which fund a large part of the schools computer system. So ENA got
the contract.

017) Economic Testimony - The Good, the Bad, and the Ugly
Article:
http://www.rrc-inc.com/articles_economic_testimony.php (undated)
"There are times in which the economic expert
is either unprepared or led into difficult positions. Likewise, there are
times in which the cross examination opens the door for further damaging
economic testimony. Over the years, we have compiled a list of some of the
goofs and some of the successes among economic experts we have observed. ".
What spreadsheet?
During trial the plaintiff's attorney during
cross examination focused upon the computer spreadsheet used by the defense's
economic expert to allegedly prove that there were zero economic damages. The
expert had relied heavily upon research assistants to construct the
spreadsheet, but under the expert's supervision. Unfortunately, the expert had
not carefully examined the calculations and was not aware of several
calculation errors. The spreadsheet was blown up as a trial exhibit, along
with an alternate spreadsheet with corrected figures. The expert's testimony
at trial was inconsistent with the corrected spreadsheet. The expert was
forced to acknowledge to the court the calculation error, and tried to explain
it was not a serious one. Yet it was too late. The jury lost confidence in the
testimony. The jury awarded the plaintiff more than $12 million in damages.
Did you copy all the way down?
A plaintiff's economic expert was claiming that
damages were to accrue over an extended period of time due to a permanently
damaged reputation. Due to an incorrect use of a copy command in the
spreadsheet, the lost profits after the tenth year of the projection became
discontinuous, abruptly decreasing in one month, then following a smooth trend
upward though the remainder of the time horizon. The economist had
revised the spreadsheet, but failed to copy the revision down all cells,
stopping after ten years. The remainder of the projection used the unrevised
formula which abruptly took the profits into the negative regions. Since the
profits were projected for a surgeon, it made little economic sense that a
surgeon would continue practicing for several years with a negative income.
Upon questioning in the deposition, the expert
could not quickly figure out the reason for the questions and admitted that,
if the projection showed it, it was quite possible for profits to be negative
for short periods of time. Problems and inconsistencies could have been
detected by the expert by simply graphing the result. However, the expert
chose not to admit the possibility of a mistake in a deposition and provided
damaging testimony instead.

surprised to find them using a wrong function for IRR calculation (Tip: There
are 2 Excel IRR functions IRR() and XIRR(). XIRR() handles non-periodic
cashflows while IRR() can handle only periodic cash flows). Over the last
