Of those variables, only three resulted significant: COICOP group index growth, competition proxy, and percentage of services.
Due to some problems with the data and the econometric methods already pointed out, Beck et al. (2009) only introduced a reduced group of variables in their multivariate analysis to explain inflation (for all the countries of their study): unemployment rate, real ULC, COICOP group index growth, competition proxy, percentage of services and real GVA per capita growth.
Alternatively, shifting gaze could reflect men's vigilance, which may vary with the presence of a partner and his attractiveness, and thus index intrasexual competition.
Indices of competition for estimating rapeseed yield loss due to Canada thistle.
Spatial or aspatial indices of competition (e.g. Lorimer, 1983; Tome and Burkhardt, 1989; Holmes and Reed, 1991; Biging and Dobbertin, 1992, 1995) are the dominant mechanism for generation of size hierarchy in many tree growth models.
To address these questions, we designed a 2-part study, with a behavioral component run outside the scanner, and a functional magnetic resonance imaging (fMRI) component run on the same stimulus set, manipulating the nonword point and 2 continuous variables indexing cohort competition and selection processes.
a) growing space (grey area) defined by location on a certain spoke and circle; b) distance-independent competition index: local stand density index (SDI l ); c) distance dependent competition index according to Hegyi (1974) and d) growing space calculated by Voronoi polygons (Turner 2014).
We presented results using the Hegyi-index as indicator for competition likewise used by Vanclay et al. (2013).
After an evaluation of a variety of competition indices, the index DRD; sum of the ratio of each of the three nearest neighbour's DBH to the subject pine divided by their distance and, amount of available light at the top of the crown (DIFNt) were found as the best overall predictors of pine stem volume growth.
The explicatory variables in the models were the inverse of diameter at breast height, a competition index for individual trees, site index, and the proportion of basal area for the respective tree species.
