Ambika. Using the latest version of DESeq2 (v1.16), the maximum likelihood estimate of the LFC will be something like log2 of the mean of normalized counts in the group with positive counts. We include a threshold on how low the expected value of the counts can go, which stabilizes the methods and prevents the LFC from going to +/- infinity.2. The log fold change can be small, but the Hurdle p-value small and significant when the sign of the discrete and continuous model components are discordant so that the marginal log fold change cancels out. The large sample sizes present in many single cell experiments also means that there is substantial power to detect even small changes. 3.The two– dimensional probability distribution f(log 2 v T, d | μ) is used below to find the expectation of log variance LV = log 2 v T, conditioned on the value of log fold change.
