The results provide evidence that the scenarios under the condition η>1 yield a hard estimation (having larger variation ranges of the MSEs than those obtained for the cases when η<1) for α and β parameters, and that the MLEs present smaller values of the MSEs under such conditions.
Second, previous studies all employed a single root age fossil constraint, treated as a hard bound, precluding an accurate estimation of error associated with this calibration point.
One of the key points was the evaluation of washing efficiency, as it is really hard to give a quantitative estimation of the dirt removed.
If one uses the full alphabet of 20 amino acids, it becomes hard to gain sufficient data for a correct estimation of these complex models.
Since not all proteins are expressed in a specific sample under a specific condition, estimation of P (I k | T, X > x ) becomes harder.
The Interpublic Group of Companies, a marketing-services company, made a similar estimation of Barbour's capacities.
It sounds like you had quite a low estimation of them already.
Getting relevant parameter estimation of a non-linear model is often a hard task from both an experimental and numerical point of view.
Though pleiotropy, which refers to the phenomenon of a gene affecting multiple traits, has long played a central role in genetics, development, and evolution, estimation of the number of pleiotropy components remains a hard mission to accomplish.
Why does Ed Miliband now use "striver" as though it were an acceptable way to describe someone, by a stranger's groundless estimation of how hard they are hypothetically trying?
We focus here on the process of structural learning, as the discovery of novel relations between genes, the environment, and disease is typically considered a harder problem of greater interest than the estimation of effect strength for a known factor.
