edata |
Normalized counts matrix with genes in rows and samples in columns. |
group |
Primary factor of interest in DE analysis, e.g., treatment groups, tissue types, other phenotypes. |
covariate |
Other variables (or covariates) associated with expression level. Input must be a matrix or data frame with each column being a covariate matching to |
link.function |
Link function for the generalized linear model, either 'log' or 'identity', default as 'log'. |
CompareGroups |
Labels of treatment groups or phenotypes of interest to be compared in DE analysis. Input must be a vector of |
simulated.pvalue |
If empirical p-values are computed, simulated.pvalue=TRUE. The default is FALSE. |
permutation |
The number of permutations used in simulating pvalues. The default value is 100. |
DE.results |
Likelihood ratio test results with test statistics, p-value, FDR, DE genes, groupwise mean expression, fold change (if two groups are compared). If simulated.pvalue=TRUE, test.results also includes simulated p-value and FDR. |
full.model.fit |
Generalized linear model with zero-inflated Exponential likelihood function, estimating group effect compared to a reference group. |
