In addition to the number ofttest options,ttests are often confused with completely different techniques as well. Here's how to keep them all straight. Correlation and regressionare used to measure how much two
Lines represent the best linear fits obtained from linear regression. P values were estimated by testing the null hypothesis of zero intercepts using an F test. P-adj, adjusted P value. Full size image In addition to separating genes by temporal dynamics, the coexpression networks also ...

using a logistic regression framework to train a bivariable model on bulk cohort 1, the resulting composite model yielded an AUC of 0.85 in bulk cohort 1 (P = 0.02) and

久经考场的你肯定对于很多概念类题目里问到的“区别和联系”不陌生,与之类似,在统计领域要研究的是数据之间的区别和联系,也就是差异性分析和相关性分析。本节我们重点关注数据的差异性分析。 我们知道,比较两个数之间的大小,要么前后两者求差,要么求比。差值大于零说明前者大于后者。比值大于1说明分子大于分母。

While the perforin-Gzm pathway is the major effector arm of CTL-mediated cytotoxicity, the Fas-FasL pathway and IFNγ secretion have also been implicated in tumor regression (Lee and Ferguson, 2003, Shankaran et al., 2001, Street et al., 2001, Trapani and Smyth, 2002). Repression of ...
