However, this conclusion has been challenged [ 13, 44], because in practice, it is difficult to design and implement a sampling protocol free of methodological bias.

Also, bringing laboratory services closer to the clinic, e.g. by implementing a sample transportation system, may enable TB case finding in Bali.
Because of this, the study has implemented a sample size re-estimation, which will occur 1 year later after the 400th patient has been enrolled or once 2000 patients have been enrolled.
This information is collected by each communication node from the latest received beacon sent by its preceding vehicle, essentially implementing a sample-and-hold mechanism.
This problem has been addressed by Erlich et al. [14] by implementing a sample-pooling pattern combined with tagging of the pools and Galan et al. [16] by combination of tags in the forward and reverse PCR primers.
Rödig and Siebert implemented a sample-changing wheel to provide fresh sample after each reaction [ 16].
Our work, however, differs from that presented in reference [ 9] in that our dataset is (i) unfettered by ascertainment bias or assumptions of a two-species model (see electronic supplementary material), (ii) uses 80K more loci and (iii) implements a sampling and analytical design intended to specifically test hypotheses of hybrid origins for the different Canis types.
In order to make inference from the BBC model, we implement a Gibbs sampling method [ 27] to draw samples from the posterior distribution of the indicator variables, which can be derived by combining equation (8) with a prior distribution on the δ and κ.
The first is to design and implement a sound sampling protocol in order to enable the collection of reliable technical data to guide the winemaker: ° Brix, berry weight, acidity and pH.
