Moreover, as one person was randomly selected from each selected household, the probability of selection also varied by household size.
First, 18 middle super output areas (MSOAs) were selected with the probability of selection proportionate to population size.
In the first stage of selection, a random sample of 342 EDs was selected with the probability of selection proportional to parish size.
A total of 720 postcode sectors were selected, with the probability of selection proportional to the number of delivery points (or addresses) in each sector.
From the solution set, some solutions are selected as "parents" with the probability of selection proportional to the rank of their objective functions.
For 30,000 iterations, pairs of genes were selected at random, with the probability of selection being proportional to activation bias.
The first stage consisted of selecting 466 clusters (primary sampling units) with the probability of selection proportional to the size; the size being the number of households in the cluster.
In the first sampling stage we selected 26 village level clusters in each region where the probability of selection was proportionate to the population size.
This PDF represents the probability of selection of each element of the individual.
(ii) Calculate the probability of selection (p_i) of each solution (Y_i) by the formula (p_i=frac{f(Y_i)}{F}).
Cost values for the intervening land cover types were determined based on the probability of selection relative to high-quality winter habitat.
