For the statistical analysis of associations of LPT trade attributes with commune infection status during 2003 to 2006, and for the analysis of the poultry trade network we used the information generated from the "buy and sell" and "buy only" LPT's.
As for trading virtual attributes, character possessions in the multiplayer game Everquest (such as a sword that an advanced player had won in a difficult level of the game) already trade on Ebay.
30 We will use advanced survey design techniques that maximise the potential for trading between attributes to enhance the data quality.
The conjoint task required the patients to trade-off attributes associated with treatments by assessing their relative importance.
Based on this framework, we provide a literature review with special focus on design trade-off attributes and methodologies.
The financial markets in European Community have demonstrated a similar HFT adoption trend as in the American and London markets, with about 25%% of equity trading volume attributed to HFT activities.
Their review also showed evidence that individuals decide sometimes whether or not to commute by bicycle by comparing cycling with other transport modes available trading-off attributes such as costs, travel time and safety.
The higher ANA probabilities among illiterate respondents, and illiterate respondents answering efficient designs, supports a priori expectations that the greater cognitive demands for trading-off attributes and their levels in efficient designs induces higher levels of ANA among lower literacy respondents.
Firstly, all LPT trade behaviour attributes were screened statistically using univariable logistic regression with commune infection status based on a p-value of 0.20, using the likelihood-ratio test.
However, this may depend on study context (Ryan and Gerard, 2002), and there is some evidence that some respondents may not trade-off attributes, but adopt simpler decision heuristics (Scott, 2002; Lloyd, 2003).
