Further, we eliminate the bias in q(th) quantile function of the t(r)-chart for both the known and unknown parameter case. In particular, the MRL-unbiased t(r)-chart is discussed in detail and compared with the ARL-unbiased t(r)-chart. It is found that the MRL-unbiased t(r)-...

一. QQ图 分位数图示法(Quantile Quantile Plot,简称 Q-Q 图) 统计学里Q-Q图(Q代表分位数)是一个概率图,用图形的方式比较两个概率分布,把他们的两个分位数放在一起比较。首先选好分位数间隔。图上的点(x,y)反映出其中一个第二个分布(y坐标)的分位数和与之对应的第一分布(x坐标)的相同分位数。因...
Thus, we take as the theoretical quantile the value where q corresponds to the ith ordered sample value. We subtract the quantity 0.5 so that we are exactly in the middle of the interval ((i - 1)/n, i/n). These ideas are depicted in the right frame of Figure 4 for our small ...

q = quantile function:分位数函数; r = random generation (random deviates):使用对应概率分布生成随机值函数; 以正太分布为例:正太分布的简称为norm 那么R语言中对应的正太分布的概率分布函数包括:dnorm, pnorm, qnorm & rnorm dnorm():输入的是x轴上的数值,输出的是该点的概率密度 ...
There are currently 4x S3 methods related to mcsim(), all of which return some portion of the ‘mcsim’ object as either a plot, hist or table (summary and quantile). For each method you can choose to set normalize=TRUE or FALSE. This will simply define the return space your simulations...
*Single variable MR fitting: only one variable, such as the 10th column variable of 'Dat,' typically indicated by the variable importance results of RFQT, for further stratification MR analysis. This can be accomplished using the DRMR package (with quantile/split points determined by the user)...
To this end, the novel Quantile Autoregressive Distributed Lag (QARDL) approach of Cho et al. (2015) is employed in modeling both short-run and long-run asymmetries between interest rate volatility and economic growth. The remaining sections of this paper are organized as follows: the “...
QUANTILE as a general term covering quartiles, percentiles, etc. arrived about 60 years after the terms it was generalising. David (2001) gives M. G. Kendall’s "Note on the Distribution of Quantiles for Large Samples," Supplement to the Journal of the Royal Statistical Society, 7, (1940...
