In addition to the households interviewed (contiguous households without sub-sampling in each of 66 clusters), research teams interviewed international relief workers, reviewed food distribution practices and discussed key issues in gender-stratified focus groups.
Individual milk samples were collected at 2 consecutive milkings (morning and evening) at 0, 1, 3, 5, 8, 11, and 14 d of the experimental period, and 2 consecutive samples in each cow were combined on each sampling day in proportion of the morning and evening milk yields.
The sampling strategy consisted of three different sampling schedules (with three sampling times in each): schedule 1: 30 min before the end of the infusion, 5 min and 3 4 h post-infusion; schedule 2: 30 min before the end of the infusion, 10 min and 5 7 h post-infusion; schedule 3: 5 min before the end of the infusion, 30 min and 20 24 h post-infusion.
Let be a vector containing samples of taken in, with sampling interval, in which case ( is an integer representing the number of samples in each symbol interval).
The sample size generated from the importance sampling function in each subspace is determined by the contribution of the subspace to the reliability sensitivity, which can be estimated by iterative simulation in the sampling process.
24 Performing correct bootstrapping without expanding the sample would require knowledge of the details of the sampling process in each county, namely stratification units, primary and secondary units, etc.
Full details of sampling methods in each country are set out below.
All investigated diseases were assessed at five sampling points in each plot, distributed in a uniform pattern.
Forward Sortation Areas (FSA, Canada) and ZIP codes (USA) defined the sampling areas in each city.
