Sentences with phrase «shape parameter estimates»

While GEV shape parameter estimates are predominately negative, qualitatively showing weak evidence for the Fréchet form of the GEV distribution, field significant differences from the Gumbel distribution in the region are not found.

The autocorrelation of the «blade» segment of «hockey - stick» shaped proxies is significantly higher than the rest of the series, this biases their estimates of autocorrelation parameters because their model assumes a stationary autocorrelation structure, making their simulated series unrepresentative of most of the length of hockey - stick series, as can be seen in this graph of lag - 1 autocorrelation coefficients.

This is visualized in figure 4 where ensemble members from the CCSM4 AR4 runs are fit with S - shaped (Gompertz) functions using the 1979 - 2011 period to estimate the parameters.

The point estimates are roughly Weibull distributed with shape parameter ~ 2.

And if you judge MRES by other criteria than variance or standard deviation, e.g. getting an interesting shape, then you are still within the realm of estimation theory (you're estimating the parameters that give you your interesting shape) but no longer in that of minimum mean squared error.

The examination of parameter estimates provided a hierarchy of contextual factors in shaping SOC.
