The RFI is one of the most informative indices in SEM (Bollen 1986).
In most cases, researchers perform exhaustive manual selection of the most informative indices.
The use of the most informative indices may improve the prediction of ischaemic heart disease mortality, and may be useful in choosing a preferred index in cardiovascular research.
The most informative indices were systolic blood pressure in men and pulse pressure in women, waist-to-hip ratio adjusted for body-mass index both in men and women, and the ratio of total cholesterol to HDL cholesterol for both men and women.
In men systolic blood pressure was the most informative index (χ12 = 16.8), followed by mid blood pressure (χ12 = 16.3), whereas in women, pulse pressure was the most informative index (χ12 = 8.8).
In relation to blood pressure, for example, mid blood pressure has been suggested to be the most informative index in relation to ischaemic heart disease mortality [ 4].
The waist-to-hip ratio (WHR) adjusted for body-mass index was the most informative index (χ22 = 13.6 and χ22 = 18.2 for men and women, respectively) whereas WHR was slightly less informative (χ12 = 9.7 and χ12 = 17.2 for men and women, respectively) (Table 3).
Certain businesses find that revenue may not be the most informative indicator of their financial performance.
Metabolic fluxes are the most informative and direct indices of the metabolic and physiological state of cells/tissues, and hence, inferring their state in different biological contexts is probably the holy grail of metabolic modeling.
Previously, it has been suggested that mid blood pressure may be the most informative blood pressure index [ 4], but in our data, this index showed relatively high informativeness in men, but not in women.
Consistent with the above, the acetylation signals, in particular H3K27ac, are the most informative for predicting the stalling index.
