由上升分布推断夏普比率

Inference on the Sharpe ratio via the upsilon distribution

Steven E. Pav

摘要:

引入了正态分布和独立χ-随机变量之和的正态分布。作为一个特殊情况,upper分布包括Lecoutre的最大素数分布。向上分布在夏普比率的频率论推断中得到应用,包括对独立样本、置信区间和预测区间的假设检验,以及它们的贝叶斯对应物。这些测试的情况下,因子模型的回报。

英文摘要:

The upsilon distribution, the sum of independent chi random variates and a normal, is introduced. As a special case, the upsilon distribution includes Lecoutre's lambda-prime distribution. The upsilon distribution finds application in Frequentist inference on the Sharpe ratio, including hypothesis tests on independent samples, confidence intervals, and prediction intervals, as well as their Bayesian counterparts. These tests are extended to the case of factor models of returns.
