In surveys using population registers as sampling frames, the proportion who were ineligible was 1 %-7 % and in surveys using address lists as sampling frames, 10 %-13 % (Table 1).
Although convenience samples are unlikely to be representative of the population being studied, random sampling techniques are seldom appropriate for use with LBW because of the inability to form a sampling frame, the small proportion of LBW within the population as a whole, and because sexual orientation is a sensitive topic for some [ 45].
Frame -1 tORFs were filtered out more effectively than frame +1 (Table 2): the proportion of frame -1 tORFX dropped from 45%to25%5% of the total after conservation filtering, and from 9% to 6% for tORFM.
In addition to these analyses we also performed a separate calculation addressing the same question: for each feature dimension, we calculated the mean feature values within the speaking character and within the whole frame and compared the proportion of the two.
The proposed method detects abrupt scene changes between adjacent frames by computing the proportion of invalid pixels with respect to the total number of pixels in the observed LR frame of size [M × N]: 1 M N ∑ k = 1 M N I ( d k ( t ) ) ≥ T h, w h e r e I ( d k ( t ) ) = 1 i f d k 2 ( t ) > γ. 0 o t h e r w i s e. (15).
For example, all mentions of percentages in the site were carefully edited to become framed in terms of the proportion of children surviving, rather than dying.
Within the frame of this arbitrary score, the proportion between the weights of "adjacent" models is fixed: in particular, the score of each model is twice that of the immediately precedent model.
Design 6 investigates the case where either the time interval between frames to be analyzed in each video is decreased by half, or the analysis per se of each frame take twice as long (i.e. about 45 seconds) which could occur if the number of variables increases, the proportion of missing frames decreases, or the complexity of frames increases.
This adjusts the proportion of frames from the video that will be exported.
