That uncertainty comes from multiple sources: sampling error in the polls themselves, uncertainty about the house effect corrections, and uncertainty about how quickly vote intentions are changing.
The uncertainty comes from multiple sources: (1) sampling error in the polls themselves; (2) uncertainty about the house effect corrections; (3) uncertainty about how quickly vote intentions are changing; (4) uncertainty about the strength of the correlations between and within clusters of states and the national level.
While large vessels such as the aorta can be visualized at necropsy, smaller arteries require multiple sampling for histology and quantification is subject to sampling error.
This technique simplifies the investigation of multiple samples, reduces experimental errors and improves experimental efficiency.
In addition, these results highlight the shortcomings of current vector detection methods: the need to acquire multiple biopsies using an invasive procedure that is prone to sampling error and is concomitantly impractical for repeated monitoring of the entire tumor.
Costs related to outcome are analysed using net-benefit acceptability curves, multiple imputation and bootstrapping, including only the uncertainty due to trial sampling error.
Simulated data had no redundancy (multiple reads per allele), therefore read count thresholds were not applied and sequence sampling error was not evaluated.
This could be attributed to sampling error, since the subsetting was only performed once, and not multiple times like the downsampling.
The consistency of the conclusions under multiple assumptions is important since standard significance tests are not applicable, due to the complexities of sampling error in the original surveys compounded with survey errors in the access information for the 6 methods.
Double and multiple stage sampling plans may be less risky in a theoretical sense showing a lower probability of sampling error, however, applications on the shop floor require intensive training and the learning curve is uncomfortably steep.
