The inclusion of the attitudes in the class allocation component of the latent class model leads to a richer picture of people׳s valuations, revealing, for example, antagonistic preferences of two distinct groups of respondents, i.e. advocates and opponents of wind power generation.
The model assigned all AA sites into three classes of 461, 206 and 120 sites with an average ω of: 0.05 (clows1: low ω, purifying selection), 0.61 (class 2: intermediate ω, nearly neutral), 1.70 (class 3: high ω, potentially positive selection) and average probabilities for the class allocation of 0.96, 0.90 and 0.88, respectively.
We evaluated whether this class allocation was consistent with the k-means clustering of the samples themselves.
Statistical analyses of the study will be conducted by a statistician blinded to the hypotheses of the study and to each class' allocation to the experimental or control condition.
The CUtLASS trials had the advantage of randomised drug class allocation, avoiding the problem in naturalistic studies where certain drugs may be prescribed for particular groups.
By Bayes' theorem, Pr (C = c | X 1 = x 1, …, X p = x p ) = Pr (X 1 = x 1, …, X p = x p | C = c ) Pr (C = c ) Pr (X 1 = x 1, …, X p = x p ). Pr C = c) can be estimated from training data and Pr X1 = x1,..., X p = x p ) is irrelevant for class allocation; the predicted value is the class that maximizes Pr X1 = x1,..., X p = x p | C = c).
In practice however this information on the fuzziness of the class membership can actually be informative, but if a hard class allocation is required, the decision can be taken to allocate the area to the most probable class.
We consider the distribution network design problem when the global round-up, single class allocation, local separate stock, local round-up, and critical level inventory policies are used.
For ease of presentation, the plots were separated according to class allocation in early childhood.
The form of the hierarchical distributions can be chosen to fit the investigation, and it would even be possible to incorporate mixtures of distributions or a class allocation methodology if the application warranted it.
Graphical displays of individual change (or stability) in class allocation over time were produced using the Risk plot command in Stata version 11.1 [ 30].
