However, for stratification on the propensity score to achieve the desired effect, the assumption of no hidden biases must hold.
Furthermore, as the SEM was based on the assumption of no hidden confounders, the potential influence of unmeasured common causes cannot be eliminated.
Thirdly, unbiased treatment effects from matching are based on the assumption of no hidden bias; this assumption might be less tenable for the subgroup with two organ systems failing, in which 36% of the DrotAA cases are treated after a delay of more than 24 hours.

Depending on their own experience of siblings and their own parents, a newborn's parents will bring all kinds of hidden assumptions to bear if told "it's a boy" rather than "it's a girl", when it pops out of the womb.
Current HMM based applications for CNA analysis rely on the assumption that increasing the number of hidden states, thereby increasing the complexity of the underlying model, will eventually result in higher CNA classification accuracy [ 10- 12].
This condition suggests that there can be a hidden assumption of recursive embedding in developing an invisible scheme - if the required capacity is not achievable in first run of E, the remaining bits can be re-embedded recursively.
A scientist, his father is skeptical of "hidden and untenable assumptions" and dismissive of his poet son's suggestion of parallels with the fratricidal war in the Mahabharata — "The Mahabharata is just a story".
The answer is because the Five Step Plan is based on a number of hidden -- and false -- assumptions.
On the other hand, we admit that the possibility of hidden confounders in GWAS data may challenge the causal sufficiency assumption.
