[求助] 门外汉请教一句文献翻译的意思。。T 。T

Gene expression proﬁling provides us with a matrix of n expression values measured for p genes where p is much larger than n, typically somewhere between one and three orders of magnitude.

没有分子生物学的基础，不能明白文献里p，n的含义，希望有大侠简单给我解释一下。顺便问一句，有人用过qp-graph么，能不能告诉我查哪一方面的书能让我理解qp-graph里面的相关算法呢？

An analogous idea with Gaussian graphical models associated to undirected graphs is to employ limited-
order partial correlations, concretely, q-order partial correlations with q < .n 2/. In this way, we can
carry out a test for the hypothesis of zero q-order partial correlation between two genes with the hope
that if they are not directly associated, their indirect association is mediated by less or equal than q
other genes.
还有这句话是什么意思？q在这里的含义是啥~感激不尽T.T
