Commands Summary AHP Menu This section summarizes the commands available in <strong>Logical</strong> <strong>Decisions</strong> for Windows (LDW). The summaries are in alphabetical order by menu. The AHP menu appears whenever you are doing an assessment using the Analytic Hierarchy Process. AHP::Cancel Cancel the AHP assessment. LDW will return you to the dialog box where you started the assessment without saving. AHP::Done Finish the AHP assessment. LDW will save the results and return you to the dialog box where you started the assessment. AHP::Estimate Ratios When Checked, LDW will estimate a ratio for each cell in the matrix that has not been explicitly entered, based on the ratios entered so far. AHP::Identify Outliers Ask LDW to identify those cells whose entered ratios differ most from the ratio computed from the diagonal of the AHP matrix. When you select the option LDW will ask you how many cells to highlight. AHP::Hide All Statistics When checked, LDW will not display any of the three statistics in the cell at the upper left of the hierarchy -- lambda-max, the consistency ratio and the consistency index. AHP::Hide Weights When checked, LDW will not display the computed weights along the matrix diagonal. AHP::Show C.I. Only When checked, LDW will only display the Consistency Index statistic in the cell at the upper left of the hierarchy. The lambda max and consistency ratio will not be displayed.
