The first factor is due to instrumental effects that include non-ideal optics, wavelength dispersion, sample transparency, axial divergence, flat sample effect, and detector resolution.
The median polishing summarization method is based on a two-factor model, which include the sample effect and probe-specific effect.
Taking into account the finite sample effect and the skewness of peak intensity distribution, the form of asymptotic score statistics (P-values) of RAId_DbS [ 13] is derived theoretically.
Sampling effects and missing data can also lead to differences in association patterns when markers are highly correlated and sample sizes are not particularly large.
The phenotypic value of a descendant animal in the latter two generations (G1 and G2) was formed by an average of the parents, a Mendelian sampling effect and a random residual.
Due to the very dry summer 2003, water volumes were lower than in other years, which lead to a stronger sampling effect and thus stronger underestimation of total ephippia production.
PLM computes ê ij, i=1,…, G, j=1,…, N, on the basis of a robust regression model allowing general probe and sample effects.
Unfortunately, non-parametric tests do not have well defined sample effect sizes and so it is not possible to use them as an absolute point of comparison that is independent of sample size.
Data was analyzed using a mixed linear model panelist, order and treatment (sample) effects.
This is true for the overall sample effect (Panel A) and also the effect for individuals unemployed for at least 26 weeks (Panel B).
