In other words, the statistic is a biased estimator if it overestimates or underestimates the population parameter. The more deviation between these values, the greater the bias. For example, a confidence interval is a biased estimator because it estimates a population parameter using a range of ...
coefficients (n = 38 independent participants). Error bars represent sample mean ± SEM. GP gain/partial, LP loss/partial, GC gain/complete, LC loss/complete. Two-way repeated-measures ANOVAs indicated that only VMPFC cue-evoked activation is affected by our experimental manipulation, w...
climate change17, the loss of Siberian research stations may be particularly detrimental for the ability to track global implications of thawing permafrost18, shifts in biodiversity, including shrubification19and carbon dynamics20. Notably, for some variables (for example, precipitation and vegetation ...
A naive approach to the estimation of α using machine learning methods would be, for example, to construct a sophisticated machine learning estimator for learning the regression function αD + g(X). Split the sample in two: main sample and auxiliary sample (why? see note below) Use the au...

For example, researchers had found that Chinese sixth graders were the most vulnerable to overusing proportionality (given the frequent practice on these types of problems at this grade level, upon first learning this topic), while eighth graders were the most proficient in proportional reasoning but...

This step moreover adds a 1.0 Illumina adaptor (for forward reads in paired-end sequencing) and a sample-specific 4-base EMOTE barcode (blue line and “XXX”, respectively) to index the molecules (different barcodes for the -RppH and + RppH pools). The barcode of the -RppH pool...

When the sample is cooled in a small field, the SEB effect and the normal EB effect combine to form the total EB. This is evident, for example, in the 5 mT cooling PSP, in which |HC−| is larger than that of the NSP. The same applies for the −5...
