To address this potential specification problem, a final step of the estimation strategy consisted in carrying out an instrumental variable (IV) approach through a two-stage least squares (2SLS) estimator.
The expression profile of these genes in different tissues and in response to several exogenous stimuli point to a potential specification in their biological roles.
The final step provides quantitative charts to compare the characteristics of these potential solutions with the specifications of the problem.
When you look at the specifications of potential contractors, make a list of questions, which you want to be answered.
In other words, the kind of potential that is built into Hasan (1978 , 1984) specifications of generic structure potential (GSP) is represented systemically here — which is, of course, in line with her theory of context.
In order to respond to a call for tenders, bidders must define and evaluate potential solutions, based upon the specifications of customer's requirements and their capabilities (skills, existing solutions, resources … etc).
Stage 1 (potential interventions) requires specification of the core elements of an intervention (e.g., objectives, target groups, activities) and may involve both descriptive and implementation studies.
Although the Bayesian approach offers distinct advantages, potential problems include specification of an appropriate prior distribution and a nonidentifiable model.
Recent studies have shown that epigenetic effects, in concert with cues from outside the NSC, play an important role in regulating the differentiation potential and fate specification of NSC (Sanosaka et al. 2009; Fig. 1).
A detailed discussion about potential problems with the functional form specifications of linear models in the context of training programs can be found in Frazis and Loewenstein (2005).
