Smaller portfolios may be limited by stock board lot constraints, which may affect the portfolio manager's ability to accurately buy or sell to certain percentage weightings.
Several contributors explored the issue of up-weighting certain variants; for example, Gagliano et al. [unpublished data] up-weighted nonsynonymous SNPs and those SNPs residing in DNase I hypersensitive sites, and Liu and Beyene [ 2014] up-weighted rare variants, regardless of their direction of effect.
An attractive feature of these approaches is that they in principle allow borrowing of information across rare and common SNPs and allow the up-weighting of certain features (e.g., up-weighting SNPs according to membership within a gene or giving higher weights to rarer variants).
However, there are differences in the items included in each of these scale, as well as variability in the weightings given to certain symptoms, reflecting the lack of consensus regarding the core features of depression.
A mean-square error is a natural choice to measure the degree of similarity of hybrid model simulations to the original ARL model, but there is a certain degree of arbitrariness in the relative weightings of error terms in the cost function.
The last male group is treated differently because it has no raw weightings, and its relative weighting is contingent on the raw weightings for the other male groups.
Weightings that emphasise the importance of certain tournaments are based on the number of teams competing, the number of continents represented (or eligible to be represented), and in the case of continental tournaments such as the Oceania Baseball Championship the relative strength of teams eligible.
PCEF will increase the weighing of certain funds as their discounts increase and will decrease weightings when the discounts shrink.
"A lot of managers are aware of the MSCI weightings, which dictate their own weightings," she said.
But we don't have London weightings on our wages".
