Which tab allows for changes in the parameters for the Discount Rate Change Interval on the IRR Matrix report?

The Valuation Intervals tab is the correct choice because it is specifically designed for adjusting parameters related to the valuation process, including the Discount Rate Change Interval on the IRR Matrix report. This tab provides users with the necessary settings to define how frequently the discount rates should be adjusted during the analysis, which is essential for accurately assessing the internal rate of return over different valuation intervals.

The other options, while relevant to various aspects of the Argus Enterprise software, do not pertain directly to the specific adjustments of the Discount Rate Change Interval. The Report Settings tab typically deals with overall report configurations rather than specific valuation parameters. The Market Analysis tab focuses on external market data and trends, and the Property Details tab provides specific information about the properties being analyzed. Thus, they do not offer the necessary controls for modifying the IRR Matrix's discount rate settings.
