| 单词 | two-stage least squares |
| 释义 | two-stage least squares A method of estimating a set of simultaneous equations, where each variable appears as dependent variable in one equation and a right-hand variable in others. Each equation is run, then each right-hand variable is replaced by the value predicted from its own equation. The system is then re-run; the results give better estimates of each equation than those resulting from the first stage. |
