std
标准差
不推荐使用 std
。请改用 timetable
。有关详细信息,请参阅 Convert Financial Time Series Objects fints to Timetables。
说明
示例
计算金融时间序列对象中每个数据序列的标准差
创建一个
fints
对象。dates_and_times = (now:now+5)'
dates_and_times = 1.0e+05 * 7.3840 7.3840 7.3840 7.3841 7.3841 7.3841
tsobj = fints(dates_and_times, randn(6,1))
Warning: FINTS is not recommended. Use TIMETABLE instead. For more information, see Convert Financial Time Series Objects (fints) to Timetables. > In fints (line 169)
tsobj = desc: (none) freq: Unknown (0) {'dates: (6)'} {'times: (6)'} {'series1: (6)'} {'07-Sep-2021'} {'12:30' } {[ 0.5377]} {'08-Sep-2021'} {'12:30' } {[ 1.8339]} {'09-Sep-2021'} {'12:30' } {[ -2.2588]} {'10-Sep-2021'} {'12:30' } {[ 0.8622]} {'11-Sep-2021'} {'12:30' } {[ 0.3188]} {'12-Sep-2021'} {'12:30' } {[ -1.3077]}
使用
std
计算标准差。tsstd = std(tsobj)
Warning: FINTS is not recommended. Use TIMETABLE instead. For more information, see Convert Financial Time Series Objects (fints) to Timetables. > In fints/std (line 29) tsstd = struct with fields: series1: 0.8807
输入参数
输出参数
tsstd
— 金融时间序列对象中每个数据序列的标准差
结构体
金融时间序列对象中每个数据序列的标准差,以结构体形式返回。
