Therefore, the estimated coefficient ( {widehat{beta}}_0 ) demonstrated that if the trading margin and credit availability variables were kept as zero or negative values, returns changed negatively with the existence of these costs (carrying costs + impact costs + other costs).
We also excluded 20,963 cases in which the number of applicants in a given month for an agency was less than three, to facilitate the calculation of our state-month service availability variables and ensure that one's own value did not contribute too substantially to the agency average.
Land availability variable has a decay pattern, which means that the available land will be run out to be used up by human settlement.
Some of these effects, driven by microclimate, self-shading, variable nutrient availability, variable transport dynamics, and branching patterns are exemplified.
Herders specified water availability, variable precipitation, insect invasion, adequate pasture, and extreme winters as the primary pastoral challenges.
Once the supply of susceptibles becomes depleted the population collapses abruptly (resource availability variable).
For example, without data on facility availability of oxytocin, the bedside availability variable represents both availability within the hospital and preparation at bedside.
However, we chose to compute a bed-availability variable by first finding the number of occupied beds each service had on each day at the two recording times, and deducting the number of occupied beds from the maximum ever recorded occupancy for that service.
Variables included in the model were pre-selected according to hypothesised relevance and data availability, excluding variables that were collinear or lacked heterogeneity.
The selection of covariates is guided by availability of variables in data set and literatures.
TALIS, data have limitations in this sense and it is not possible to properly test this hypothesis considering the availability of variables.
