A Comparison of Alternative Methods of Estimating constant Dollar Depreciation.
比较了分层法和平均年龄法在估算不变美元折旧时的准确性，发现分层法误差、偏差和方差更小。
Abstract ABSTRACT: Previous research has questioned the use of COMPUSTAT capital expenditures data to layer fixed assets for the purpose of estimating constant dollar depreciation. This note compares the layering technique with the more popular alternative, the average age method. Estimated amounts were compared with actual data reported under FASB #33. The results indicate that the layering method provides estimates that exhibit less error, bias, and variance.
