δ2H and δ18O of ground water, and to a lesser extent tap water, reflected the δ2H and δ18O of long-term weighted annual precipitation at the two GNIP stations in South Africa.
In order to assess the importance of short or long term shocks we weighted the variance of the cyclical component ((sigma_{epsilon}^{2})) given the probabilities, from which we obtain that it represents 93%% of the variance in output.
Over the long term, many financial advisers say, funds weighted more toward stock portfolios may well outperform those with more bonds.
Therefore, level of care weighted yearly inpatient long term care costs were calculated.
The commission considered but rejected doing away with its policy of requiring bond funds with names that include "short term," "intermediate term" or "long term" to have certain dollar-weighted average maturities -- less than three years for short-term funds, 3 to 10 years for intermediate term and more than 10 years for long term.
Capital usage cost Weighted sum of long term interest rate with banks and other long term debt plus the industry-specific depreciation rate minus the investment inflation rate.
To overcome this limitation, we hypothesized that shallow phreatic groundwaters in Mexico could be used as an isotopic integrator of long-term seasonally weighted precipitation inputs to the landscape to aid in calibrating spatial H and O isotope datasets for terrestrial, biological and hydrological research.
Third, we consider commonly-used "static" regressions, with a treatment dummy instead of a full set of leads and lags around the treatment event, and we show that OLS does not recover a weighted average of the treatment effects: long-term effects are weighted negatively, and we introduce a different estimator that is robust to this issue.
Locations with more long-term data are weighted more heavily, but even reefs with one survey were also able to be included in the model.
Our analyses of the effects of long-term and individually weighted short-term BS exposure assumed that the pattern of intraurban spatial variations in long-term average BS exposure in 1970 1979 was largely sustained over the subsequent 1980 1998 period, which could not be verified because of the substantial reduction in the BS monitoring network during this later period.
