Final answer:
Modern computer-based financial planning models are equipped to perform sensitivity (what-if) analysis, contrary to the statement that they have difficulty in incorporating such analysis. These tools are essential for understanding the impact of varying financial variables and making informed decisions.
Step-by-step explanation:
It is false that most computer-based financial planning models have difficulty incorporating sensitivity (what-if) analysis. While individual-based models (IBMs) can be complex and demanding in terms of computing power, modern financial planning models are designed to handle sensitivity analysis effectively. These models utilize simulation techniques to explore various scenarios in financial planning. Sensitivity analysis is a key component in understanding how different variables can impact financial forecasts and decisions. Financial models are typically created with the ability to alter parameters and observe the effects, making what-if analysis an integral part of financial planning.
