Let's talk about valuation. Compare and contrast the DCF, Comparable Company Analysis (Comps), and Precedent Transactions methodologies. For each, discuss its key advantages and disadvantages, and describe the situations where it is most and least applicable. Finally, how would you typically integrate these different approaches to derive a comprehensive and reliable valuation range?

在对一家公司进行估值时，我们通常会使用多种方法，例如现金流折现法（DCF）、可比公司分析法（Comps）和先例交易分析法（Precedents）。请你详细比较这三种主流估值方法的优缺点，并讨论在实际应用中，你将如何选择或结合使用它们，以得出一个全面且可靠的估值区间。在你的讨论中，请特别说明每种方法最适用和最不适用的场景。
