There are some documented cases, however, where exceptions to this assumption exist.
Statistical tests of this assumption exist but tend to have low power and therefore not commonly conducted in practice.
But merely noting that this symmetrical assumption exists does not go far enough.
13 Approaches to estimating efficacy without making this key assumption exist, and are becoming increasingly popular.
I guess I am still not sure as to why, truly, these assumptions exist, but I have no doubt that our fetish with money and the dangerous idea that "net-worth = self-worth" is tied to them.
Under this assumption, there exists an orthonormal basis ({e_m}_{mge 0}), the spectral measure (E_3) is defined on the (sigma )-algebra of all subsets of ({mathbb Z}_+), and (E_3({m})) is the orthogonal projection onto the one-dimensional space spanned by (e_m).
Despite this assumption, reports exist that Steatornis caripensis are occasionally seen roosting during the daytime in canopy trees [20], [21] Steatornis caripensis are known to carry seeds over large distances back to their respective caves [15], [17], [22], [23].
While a tree representation is convenient for computational purposes, methods that relax this assumption already exist, such as phylogenetic network reconstruction.
Given the lack of information on this in KSA, formative research through qualitative research methods is needed, as no assumptions exist regarding the reasons behind seeking healthcare, or the lack of care-seeking, among Saudis.
