What are some common techniques used in stress testing forecasts? Select all that apply.Scenario analysis, where alternative sets of assumptions are used to generate different forecast outcomes.Sensitivity analysis, where individual assumptions are varied one at a time to assess their impact on the forecast.Monte Carlo simulation, where random variations are applied to multiple assumptions simultaneously to generate a range of possible outcomes.Difference-in-Difference analysis, which estimates the causal effect of a treatment or intervention by comparing the changes in outcomes over time between a group that is exposed to the treatment and a group that is not.
