First, the possibility of having wrongly classified a woman as being dead or alive exists, due to possible errors in the Mortality Information System.
The main reason for two of the previous studies being negative was small sample size, making them liable to type II error, i.e., missing an effect when one exists due to a small sample size.
Firstly, negative studies are often due to type II errors, that is inability to detect a difference when one actually exists, due to small sample size.
Sometimes, no feasible solution exists due to bandwidth limitations and/or clients with poor channels that require forward error correction (FEC) codes with exceedingly large overheads.
High fluctuation of error estimates exist due to small sampling window sizes with dimensions of 2 to 10 pixels (Figure 6).
Consequently, measurement errors may exist due to social desirable answers or lack of valid recall [ 72].
The original length error (25.9 mm) existed due to bone angulation, which was corrected during surgery, and due to bone loss as a result of the fracture and the healing process.
Systematic errors associated with each individual instrument exist due to non-perfect alignment (collimation errors) and magnetometer offset.
Since the third steady state found in Step 2 was obtained by a numerical method, it may not exist due to the computational error.
Other odometry errors, while the robot movement, may also exist due to unequal wheels diameters, joints misalignment, backlash and slippage in encoder pulses [24].
