An EFA with four factors revealed one hyperplane item in several solutions (item 37) while Kappa = 5 led to the least number of complex items (items 5, 17, 27, 33, 36).
Based on recommendations by Brown [ 24] and Gorsuch [ 25], the Oblimin power parameter δ was systematically altered between user-defined values of -10, -5, -1, and 0 to 0.8 to find the solution with the least number of complex items, i.e. items with cross-loadings of >.30 on more than one factor, and hyperplane items, i.e. items without loadings of >.30 on any factor.
In summary, LR and HLR flag the most number of items as DIF-present items, and the testlet model flags the least number of DIF-present items by significance tests.
In the case of LU policy, the context item which has been accessed the least number of times.
When space is needed in the already full cache for a newer context data item, the LU cache replacement policy removes an existing item from the cache that has been accessed the least number of times.
Item 7 ('Were you breathless today?') was considered relevant by the majority of patients (ACO: 16/20, COPD: 9/10), whereas Item 13 ('Last night, was your sleep disturbed?') was considered relevant by the least number of patients (ACO: 10/20, COPD: 5/10).
The least number of links the better.
When performing factor analysis it is recommended that the number of participants in the sample be at least five times the number of items in the measure [ 35].
Domain scores of the EORTC QLQ-PR25 were linearly transformed to a 0 to 100 scale based on its scoring manual, which requires answering at least half of the total number of items in the domain.
