This ceiling effect results in a censored dependent variable, indicating that values higher than a certain threshold were not measured, which in the case of EQ-5D utilities is 1.
A ceiling effect results in a positively skewed distribution of measurements, limited ability of the measure to discriminate among subjects at the upper end of the scale, and attenuated responsiveness to improvements in health in longitudinal studies.
Wind sweeping around such a cavity erodes the walls, floor, and ceiling, resulting in a bottle-shaped chamber usually of greater diameter than the entrance.
However, the supply jet was found to be less efficient at mixing the air near the ceiling, resulting in higher temperatures in this zone than with higher Archimedes numbers.
But her most egregious error, of course, is misjudging the stability of that ceiling—resulting in an ungodly tumble best viewed in GIF form.
Firstly, the estimates for the main effects of the other interventions (analgesia, dosing, steam) suggested no effect of these interventions (therefore a ceiling effect resulting in a negative interaction was unlikely).
Principal amongst them are (a) very limited coverage of memory function, (b) a ceiling effect, resulting in inability to differentiate moderate from high functioning, and (c) absence of information about some aspects of cognitive function required for dementia diagnosis using internationally agreed criteria (DSM-IV [ 7]; ICD-10 [ 8]), namely perception and executive function.
However, the memory test used in that study (Brief Visuospatial Memory Test Revised) [ 25] consisted of only six items and six associations in each trial and the mean score of the control group on associative memory was 5.1 in Trial 2 and 5.5 in Trial 3. Thus, there might have been a ceiling effect, resulting in a non-significant interaction between learning trial, group, and memory type.
An explanation of this apparently perverse behaviour was offered: "The Ministry of Finance encourages the use of SWAp, but currently the approach of the Ministry of Finance [with]... sectoral budget ceilings results in threats to the sector, not only because there is insufficient funding to the sector at the moment, but also because it encourages the sector to seek funds elsewhere, off budget.
