To conduct the first step, several statistical procedures have been developed, including the Mantel-Haenszel method (MH), logistic regression (LR), the standardization procedure, and IRT (see a review by Clauser and Mazor, 1998).
This evaluation approach is based on an assumption of zero moving costs, making the value an upper limit for the individual's WTP.9 In this study we only conduct the first step and, therefore, estimate the monetary values using the hedonic price function.
First, an assessment of the total EIP emissions' inventory and impacts is conducted; the second step, focusing on the sustainability benefits of combined heating and power (CHP) plants and photovoltaic technologies, developed a multi-objective mathematical model including both economic and environmental objectives in a Pareto-frontier optimisation analysis.
In order to identify the miRs differentially expressed between the tumoral and the peritumoral areas, we conducted the first step of the microarray analysis on 20 patients from the RENCI and 19 from the SVH for a total of 39 tumors and peritumoral matched samples.
Then a living polymerization of monomers was conducted in the second step of polymerization.
If the regression variable did not enter into the model, the corresponding coefficient was set at 0. Based on coefficient estimation, one-dimensional scanning is conducted in the second step, which is similar to the second step of inclusive composite interval mapping (ICIM) [33], [34].
In such a procedure that deals with categories, qualitative analyses are conducted first, whereas the second step consists of quantitative procedures which, in a third step, need to be interpreted qualitatively again (Mayring 2011, p. 5).
Prior to collecting quantitative data on preferences, qualitative pre-studies are often conducted in the first step of a research study with a mixed methods approach (e.g., identifying relevant attributes and levels in focus groups for developing choice sets in discrete choice experiments [DCE]).
In general, the two-step procedure helps to reduce but may not exclude all false positive due to 4.2 billion of tests were conducted in the first step.
The SGR was conducted as the first step in the development of a new guideline on chronic heart failure for use by family physicians in Germany.
