In k-means clustering, the number of clusters k is an input parameter, and an inappropriate choice of k may yield poor clustering results.
Careful choice of control parameters may yield some "Earth-like" overlap of dipole-dominated reversing dynamos (Olson 2007a; Wicht et al. 2009).
Furthermore, there are limitations of querying respondents about the specific characteristics of a hypothetical vaccine; research employing conjoint analysis [ 5, 6, 49, 51, 58, 59] and discrete choice experiments [ 60] may yield better insight into relative valuations of various vaccine characteristics, project their impact on future acceptability, and inform targeted social marketing campaigns.
For example, the previous study employed a single conformer per compound, which may not be sufficient for reliable evaluation of 3-D similarity between compounds, as the choice of a different conformer may yield substantially different similarity values and makes the selection of an appropriate conformer a significant consideration.
In addition, systematically examining, how other factors, particularly attitudinal and motivational variables that influence food choice, may be changed in order to achieve healthier food choices in different target population groups, may yield valuable information.
Just as decisions about the dimensions of railroad tracks determined the size and velocity of trains for decades to come, he argues, so choices made about software design now may yield "defining, unchangeable rules" for generations to come.
In the future, having the choice to use different but complementary standards may yield potential advantages, but currently their multitude is perceived as a constraint.
So the choice of objective or subjective measures of realized access may yield different assessments of the importance of a process variable and, ultimately, of the equity of access to health-care services.
If the team has a history of conflict, technology choices that limit the opportunities for real-time emotional exchanges may yield the best results.
