the coefficient of variation for each district would be 0.
GCMs underestimate the observed variability (expressed by the standard deviation for temperature and
the coefficient of variation for precipitation) in 73 % of cases for temperature and 90 % for precipitation (Fig. 6), and the observed Hurst coefficient in 75 % of cases for temperature and 83 % for precipitation (Fig. 7).

To assess the consistency
of the tissue PMI prediction
for a given individual we compute the

In Dallas, Fort Worth, and Houston, the
coefficients of variation were nearly always more than 0.15, meaning that one - third

for a school
of 500 when average spending is $ 3,000 per pupil).
In contrast, Austin had a
coefficient of variation near 0.15

for three years, from 1997 — 98 to 1999 — 2000.
Ohio also ranks 32nd
for its
coefficient of variation, at 13.7 percent, which shows moderate
variations in spending across school districts.

coefficient of variation of 14.4, indicating moderate disparities across districts in education spending.
In addition, an «equity factor» is calculated
for each state, based on a weighted
coefficient of variation.
It's almost certainly close to linear
for small
variations, but the basic nonlinearity means that we don't know a priori the
coefficient of this linear relationship.
Dobson measurements suffer from a temperature dependence
of the ozone absorption
coefficients used in the retrievals which might account
for a seasonal

of ± 0.9 % in the middle latitudes and ± 1.7 % in the Arctic, and
for systematic errors
of up to 4 % [Bernhard et al., 2005].
I looked at the (raw) annual ring widths (in excel)
for L00131 - 4 and the annual SD
of the widths seems to increase when the trees put down larger rings — their
coefficient of variation looks pretty trendless with time.
Note that these figures are the averages, and there would be
variations for each coal lease based on its energy content (BTU / lb), type
of coal and CO2
coefficient, and the period over which each coal lease may be mined and burned.
Note by the way that MMH is ambiguous on the existence
of modelling error: on the one hand they estimate separate, different b
coefficients for the different models, on the other, estimate their variances from the temporal
variations around those individual model trend lines only.
