Peursum [18] uses the inference of missing data to segment higher level activities into lower level actions.
We then stratified the six care-needs levels into lower and higher care-needs level groups and examined the association between the VNS and client characteristics.
Then, we stratified the six care levels into lower care-needs level subgroups (care support level or care needs level 1-2) and higher care-needs level subgroups (care needs level 3 and 5).
To determine whether age-related changes in HSP mRNA levels translate into lower levels of HSPs, we treated mice with one acute dose of HSP990 (12 mg/kg) or vehicle and harvested tissues 20 h later.
Transcript changes associated with variable coregulation levels resulted into lower coefficients of variation by array quantification (CVarray = 0.19 in amygdala and cingulate) compared to qPCR values (CVqPCR = 0.37; p<0.005 in amygdala; p<0.0001 in cingulate, two-group t-tests).
Education level was divided into lower than college level and college level or higher.
Parents' educational level is divided into lower, intermediate and higher education.
Educational level was stratified into lower (9 years or less the length of compulsory education in Sweden), intermediate (10 12 years upper secondary) and higher (college or university).
An outstanding issue here that we do not directly address in this paper is how to map high-level system requirements into lower-level metrics that can be measured and managed.
I failed math and science but excelled in English, but I was never put into higher level classes like I should have been, and never put into lower level math classes that were necessary for me.
