English to Russian Tech/Engineering Mathematics & Statistics Моделирование

Речь идет об итерационном моделировании траектории пробуриваемой скважины.

Как в статистике именуется "statistical bias"? В лоб "статистический/ое сдвиг смещение" почти не гуглится...

Контекст:
"
If the predicted values identified in block 105 are significantly different from the measured values at the second survey station, as determined at block 107, a correction factor can be applied and the predicted values recalculated.

For example, in block 111, if the comparison is not favorable (i.e., block 107=NO), a STATISTICAL BIAS can be applied to a correction factor. The predicted drill string response is contemporaneously recalculated by applying the correction factor with the STATISTICAL BIAS. In some situations, for example, soft formations around a bottom hole assembly would increase inclination more slowly when steering to increase inclination (and would lose inclination more quickly on a reciprocal setting) than the base model estimates.

A STATISTICAL BIAS can be determined (e.g., using probability algorithms) and used to generate a correction factor to offset such a scenario. Optionally, the correction can be applied to the portion of the well between the survey instrument and the bit to give a better prediction of the wellbore position at the bit. In some embodiments, the foregoing is iterated – i.e., the steps set forth in blocks 103, 105, 107 and 111 are repeated, until the predicted inclination and azimuth are within the acceptable error range from the measured values.
