random walk process meaning in English
无规行走过程
Examples
- Emh is established on the following three presuppositions : rational investor , efficient market and random walk process
Emh是建立在理性投资者、市场有效和随机游走过程这三个核心前提假定基础上的。 - The results show that saastamoinen / niell model can remove the most of the tropospheric delay and then significantly improve the kinematic positioning solutions ; the ionosphere which is modeled on random walk process can also improve the kinematic positioning solutions ; however , the troposphere which is modeled on random walk process will bias the kinematic positioning solutions
结果表明，对流层模型改正可以大大改善定位结果的精度，不过仍存在未模型化的对流层延迟误差。将电离层延迟作为随机过程来处理，可以提高定位精度；而将对流层延迟作为随机过程来处理，则会影响定位精度。 - The results show that the ionosphere - weighted model or the tropospheric estimation , integrated with the partly - weigthed least squares , can improve , the success rate and the reliability of ambiguity resolution ; however , if the ionospheric delay or the tropospheric delay , which is modeled on random walk process or first - order gauss - markov process , is estimated with the kalman filter , it will reduce the success rate and the reliability of ambiguity resolution
将电离层延迟作为零均值的随机游走过程(电离层加权模型) ，将对流层延迟作为静态参数，采用非递推形式的加权最小二乘法来估计，可以提高模糊度解算的成功率和可靠性。
