initialBiasZ

Gets Z-coordinate of bias used as an initial guess and expressed in meters per squared second (m/s^2). This value is determined once the calibrator starts. If sensorType is AccelerometerSensorType.ACCELEROMETER_UNCALIBRATED, this will be equal to the value used internally by the device as part of the accelerometer hardware calibration. If sensorType is AccelerometerSensorType.ACCELEROMETER, then accelerometer sensor measurements are assumed to be already bias compensated, and the initial bias is assumed to be zero. If isGroundTruthInitialBias is true, this is assumed to be the true bias, and estimatedBiasZ will be equal to this value, otherwise estimatedBiasZ will be the estimated bias after solving calibration, which will differ from estimatedBiasZ.
