However, existing reliability importance measures, which are available as a by-product of reliability analysis by first-order reliability method (FORM), may not capture the contributions of random variables accurately when the limit-state surface shows a large curvature around the design point or multiple critical subdomains exist in the failure domain.
For instance, they refer to residues from nature conservation measures, which are available for energy (Germany).
In addition, they choose to use the most famous cluster analysis methods and distance measures, which are available in statistical packages, without evaluating the validity of different conditions.
It is therefore necessary to investigate whether single area deprivation measures, which are available at all time points, or new indices based on measures available at all time points, are associated with physical capability in the same way.
For income and food security measures of SEP, which were available for all age groups, our final sample size was 4739 for BPA and 3953 for PFCs, after excluding those with missing data for the variables of interest (see Additional file 2).
Finally, we considered scores on the Digit Symbol Substitution Test (DSST) (Wechsler 1997) as a measure of cognitive function, which were available for participants ≥ 60 years of age.
Yields of NNN and NNK from smoke and tobacco filler, which is blended and cut tobacco filled in a cigarette tube, together with cigarette design parameters, were measured for 11 commercial cigarette brands, which were available in Japan from 2009 to 2013.
The PCK1 risk allele (rs8192708G) does not impact our baseline cognitive measure, SDMT, which is available in a subset of 318 subjects (beta = −1.23, P = 0.36).
In this survey we used the EQ-5D, a validated generic instrument for measuring HRQoL, which is available in more than 50 languages.
The same logic applies to the ability measures, which were estimated using all available information.
