In the final step of the analysis the factor interpretation was checked with the explanations given by participants during the Q sort interview.
The NS model provides parametric curves that are flexible enough to describe a whole family of observed term structure shapes and is consistent with a factor interpretation of the term structure (Litterman and Scheinkman 1991).
The correlation circle was superimposed on the factorial map of individual proximities to facilitate factor interpretation.
In order to facilitate factor interpretation, some factors were, in addition, judgmentally rotated to minimize negative loading.
24 Following the process of factor interpretation outlined by Hair et al 24 we conducted the analysis in five steps.
Factor interpretation was based upon a thematic reading of statements and their position in the context of all other statements in the final factor arrays.
The presence of key marker ions, for example m/ z 44 for OOA or m/ z 60 for BBOA, is another useful criterion for factor interpretation [ 14].
The modified version of the WHO conceptual framework of health system building blocks [ 26] was used wherever applicable to assist in factor interpretation.
According to Jeffrey's Bayes factor interpretation, 16 outlier markers were significant at "strong" and "substantial" thresholds, respectively, with 27 markers significant at "the barely worth mentioning" threshold.
