英文摘要：
  We give a complete algorithm and source code for constructing general multifactor risk models (for equities) via any combination of style factors, principal components (betas) and/or industry factors. For short horizons we employ the Russian-doll risk model construction to obtain a nonsingular factor covariance matrix. This generalizes the heterotic risk model construction to include arbitrary non-industry risk factors as well as industry risk factors with generic \"weights\". The aim of sharing our proprietary know-how with the investment community is to encourage organic risk model building. The presentation is intended to be essentially self-contained and pedagogical. So, stop wasting money and complaining, start building risk models and enjoy!

中文摘要：
我们给出了一个完整的算法和源代码，用于通过风格因素、主成分（Beta）和/或行业因素的任意组合构建通用多因素风险模型（股票）。对于短期，我们采用俄罗斯玩偶风险模型构造，以获得非奇异因子协方差矩阵。这概括了异质风险模型的构建，包括任意的非行业风险因素以及具有通用“权重”的行业风险因素。与投资界分享我们的专有技术的目的是鼓励建立有机风险模型。该演示文稿基本上是独立的和教学性的。所以，停止浪费金钱和抱怨，开始建立风险模型，尽情享受吧！
