One variable of interest: This is not correlation or regression, where you are interested in the relationship between multiple variables. With a t test, you can have different samples, but they are all measuring
To further explore to what extent T cell composition and frequency is distinctive for different B-NHL entities and tumour-free LN, we built classifiers using LASSO-regularized multinomial logistic regression and estimated classification accuracy using nested leave-one-out cross-validation (Fig.3eand Ext...
While the major clinical breakthroughs in reversing T cell exhaustion have been achieved in cancer, much of our understanding of the molecular mechanisms of T cell exhaustion stems from studies of chronic viral infection, most notably with strains of the lymphocytic choriomeningitis virus (LCMV) in m...
In linear regression, the t-statistic is useful for making inferences about the regression coefficients. The hypothesis test on coefficient i tests the null hypothesis that it is equal to zero – meaning the corresponding term is not significant – versus the alternate hypothesis that the coefficient...

Furthermore, we adopt the parameterization in [30], meaning that cov(Zi)=Σi and the density function is given by (5)f(zi)=Kdi(η)|Σi|−1∕2{1+c(η)δi2}−12η(1+ηdi),where Kdi(η)=c(η)πdi∕2Γ12η(1+ηdi)Γ12η,with Γ denoting the gamma function, c(η)=...
It means that MPG is linearly proportional to weight and acceleration and a constant value. But I don't understand how? I mean I don't understand what these parameters (Estimate, SE, tStat, pValue) tell me? How should I make the function of th...
Other notes on variable construction are as in Table 1. P-values come from a regression of each variable on treatment, with standard errors adjusted for heteroskedasticity. The migrants are half female with an average age of 38. The mean number of years in the United States is 11, so the...

However, as a sanity check two additional tests were performed for each gene, one being a likelihood ratio test based on a logistic regression model with no covariates and the other being a t test. The likelihood ratio test demonstrated moderate infla- tion, presumably due to population ...
