R help - May 2006 - using parnor (lmomco package) - output

Hi,
   
  I am using parnor function of lmomco package. I believe it provides mean and
std. dev for the set of data. But the std. dev provided does not match with the
actual std. dev of the data which is 247.9193 (using sd function).  Am I missing
something here?
   
  > lmr <- lmom.ub(c(123,34,4,654,37,78))
> parnor(lmr)
$type
[1] "nor"
  $para
[1] 155.0000 210.2130
  > sd(c(123,34,4,654,37,78))
[1] 247.9193
> mean(c(123,34,4,654,37,78))
[1] 155
> 
  TIA
  Sachin

parnor provides an estimate of the standard deviation of the normal
distribution, but this estimate is not the sample standard deviation.
