Given the variability of the year-by-year results, Professor Seyhun cautions that it's not clear whether insider purchases are more profitable today than they were 30 years ago.
This degree of closure permitted detailed tracking of carbon dioxide, oxygen, and trice gases such as nitrous oxide and ethylene over the seasonal variability of two years.
We compare the long-term average spatial patterns, and interannual variability of water-year total precipitation, as well as multi-year trends in precipitation across the datasets.
There is still plenty of variability year to year, with the recent quiet stretch including, for example, the devastating Hurricane Andrew in 1992.
We now examine the variability of five-year survival of the 2007 St Gallen Risk Classifications utilizing the ER/PR/HER2 subtypes.
The average distance between Neptune and the Sun is 4.50 billion km (about 30.1 AU), and it completes an orbit on average every 164.79 years, subject to a variability of around ±0.1 years.
Using as a reference the previous estimates which exist of excess respiratory mortality in England and Wales, our estimates appear to be a valid reflection of variability between years and between age groups in influenza-attributable mortality.
Analytical variability of measurements between year 1 and year 2 can be approximated by the 22% difference in ∑PCBs in the NIST SRM 1957 extracted and analyzed in year 1 and again extracted and analyzed in year 2.
As a measure of cohort variability among years (i.e. temporal variability), we used coefficients of variation following Sokal and Rohlf (1981), which incorporate corrections for small sample sizes.
Although their key ideas in each of the seven areas of knowledge of variability cover all years of schooling, the first three were especially relevant to our study, as was the last: (i) developing intuitive ideas of variation; (ii) describing and representing variability; (iii) using variability to make comparisons and (vii) considering variability as part of statistical thinking.
Flexibility to change feed demand quickly when conditions dry may reduce the variability of income between years (i.e. reduce risk) in comparison to the average farm in the region represented by a regional monitor farm model.
