其中,固定因子(fixed factor)是指该因子在样本中所有可能的水平都出现了,即该因子的所有水平均列出了,无需外推。随机因子(random factor)是指该因子的所有可能的水平在样本中没有都出现,需要进行外推。可见固定因子和随机因子是由试验设计决定的,所以我们可以根据试验设计的不同,将同一因素视为固定因子或随机因子均...

We show that many volatility models with heavy tails in financial work can be viewed as the GLM class of models with random effects in the dispersion. Hence, the h-likelihood approach, which provides efficient and simpler algori...

1) The null hypothesis is on the boundary of the parameter space,i.e., you test whether the variance for the random effect is zero. Forthis case the assumed chi-squared distribution for the LRT may *not*be totally appropriate and may produce conservative p-values. There issome theory rega...

Therefore, we opted to analyze the overall effect size (Pearson's correlation coefficient r) for the association between each primary good and global well-being, using a multi-level random effects model. The meta-analyses were conducted in R (a statistical software environment; version 3.6.3) ...
