Asset classes with expected return, standard deviations, and correlations for three regimes

We consider 15 different asset classes with expected returns ranging from 2% to 11%, standard deviations from 1% to 15%, and correlation matrices for three different regimes C,N,G.本数据集涵盖15种不同的资产类别（asset classes），各类资产的预期收益率（expected returns）区间为2%至11%，标准差（standard deviations）区间为1%至15%，同时提供了C、N、G三种不同状态下的相关系数矩阵（correlation matrices）。
