With the baseline controls in X, the factor model estimates imply the predictive effects and.

Not exact matches

Provided that the estimates entered on the forecast page are based on market consensus projections, the market - implied GAP represents the forecast horizon needed in a DCF model to arrive at a value equal to the current market price.

All estimates were pooled by using fixed - effect models; differences < 0 and ratios < 1 imply a beneficial effect of breastfeeding.

By design, SGP models do not purport to provide causal estimates of teacher effectiveness (though this does not necessarily imply that they are less accurate measures); they are intended as a descriptive measure of what is — of test score gains relative to other students who scored similarly in the past.»

The sea - level estimates are consistent with those from delta18O curves and numerical ice sheet models, and imply a significant sensitivity of the WAIS and the coastal margins of the EAIS to orbital oscillations in insolation during the Mid-Pliocene period of relative global warmth.

For precisely this reason, the numerous proxy and model - based estimates of the variations in the average temperature of the Northern Hemisphere (not just just the Mann et al reconstruction, as implied by your comment) show far more modest temperature changes than those typically interpreted from specific proxy records from any one region.

This implies that the estimates of ocean heat content changes over the last 10 years are the most accurate that we have had to date and thus provide a good target to compare against the models.

I agree that the models tend to show less decadal ocean variability than observed (given the obvious caveats on the observational side), but absolutely disagree that this implies that longer term estimates are off.

The current letter also implies that emissions from shale gas are higher than those for conventional gas, a notion convincingly dispelled by last year's University of Texas study, sponsored by the Environmental Defense Fund, that measured actual — not estimated or modeled — emissions from hundreds of gas wells at dozens of sites in the US.

This implies that the model estimate is too high.

In fact, under reasonable alternative assumptions, one of the models used to estimate the SCC provides a negative estimate of the SCC — implying that there are net benefits to global warming, which would argue for subsidizing, not taxing, CO2 emissions.

To the extent the aerosol cooling estimates in the climate models are accurate, potential intensity theory (discussed in the previous post) implies that hurricane intensities shouldn't have started to increase at all until the 1980s or 1990s, even though by that point the planet had warmed quite a bit.

This implies that «the next two decades» could mean a 2007 - 2027 interval or even a 2008 - 2028 interval, or alternatively, it might simply mean an interval estimated from model projections in 2005 as you suggest.

In physical sciences, where an OLS regression model with normally distributed errors is validly used to estimate a slope parameter between two variables with observational data, errors in the regressor variable contributing a small part of the total uncertainty, it is usual to accept the uniform prior in the slope parameter (here Y) implied by the regression model.

These models are structurally unstable in various ways that are not yet well explored, and this implies a level of irreducible imprecision in their answers that is not yet well estimated.

As well as this simple estimate from heat balance implying a best estimate for ECS of approximately 1.6 °C, and the reworking of the Gregory 02 results suggesting a slightly lower figure, two good quality recent observationally - constrained studies using relatively simple hemispheric - resolving models also point to climate sensitivity being about 1.6 °C:

Put in a two - hemisphere energy - balance model and using observed hemispheric temperature changes and ocean heat uptake changes you can easily arrive at an independent total aerosol forcing estimate - one that also implies small net total aerosol forcings that are reasonably consistent with the latest observatiional findings.
