The simulation study shows that ignoring random effects in modeling can result in unreliable factors identification and estimation.
Hence unreliable friction factor value is given by using the two-third principle for this case.
13 Histologic subtype was reported to be an unreliable prognostic factor, and age was deemed a possible indicator as some studies suggest that elderly patients with advanced NSCLC have poorer outcomes.
However, these ratings may be unreliable because of factors such as study design, expectations and emotional state.

Last November, Haradinaj was acquitted a second time; the judges cited Eighty-one's "unreliable" statements as a factor.
Since some fragments were occluded, the observation model of these regions is unreliable and the forgetting factor is determined to be equal to 0. Therefore, the observation model is stopped from updating.
As described earlier, this is unreliable because the proportionality factor between copy numbers and fluorescence intensity (k) can differ between targets.
Despite studies which support findings from self-reported information [ 3, 10], for some scholars and practitioners self-reported data are perceived to be unreliable estimates of health factor prevalence. Moreover in recent years, telephone survey response rates have declined [ 5, 11].
A senior I.R.S. spokesman, Terry L. Lemons, said that no one should pay attention to the new data, which he said was "unreliable because of seasonal factors" that affect audit rates.
