Single-cell transcriptomics reveals gene expression heterogeneity but suffers from stochastic dropout and characteristic bimodal expression distributions in which expression is either strongly non-zero or non-detectable. We propose a two-part, generalized linear model for such bimodal data that parameterizes both of these features.

This compositional bias confounds inference of absolute abundances. Commonly used count data normalization approaches like library size scaling/rarefaction/subsampling cannot correct for compositional or any other relevant technical bias that is uncorrelated with library size.

To determine which changes in the host cell genome are crucial for cervical carcinogenesis, a longitudinal in vitro model system of HPV-transformed keratinocytes was profiled in a genome-wide manner. Four cell lines affected with either HPV16 or HPV18 were assayed at 8 sequential time points for gene expression (mRNA) and gene copy number (DNA) using high-resolution microarrays.

DNA methylation offers an excellent example for elucidating how epigenetic information affects gene expression. β values and M values are commonly used to quantify DNA methylation. Statistical methods applicable to DNA methylation data analysis span a number of approaches such as Wilcoxon rank sum test, t-test, Kolmogorov–Smirnov test, permutation test, empirical Bayes method, and bump hunting method.

The post-genomic era with its wealth of sequences gave rise to a broad range of protein residueresidue contact detecting methods. Although various coevolution methods such as PSICOV, DCA and plmDCA provide correct contact predictions, they do not completely overlap.

Conventional differential gene expression analysis by methods such as student’s t-test, SAM, and Empirical Bayes often searches for statistically significant genes without considering the interactions among them.

Expression quantitative trait loci (eQTL) analysis identifies genetic markers associated with the expression of a gene. Most existing eQTL analyses and methods investigate association in a single, readily available tissue, such as blood.

Combining genomic data sets from multiple studies is advantageous to increase statistical power in studies where logistical considerations restrict sample size or require the sequential generation of data. However, significant technical heterogeneity is commonly observed across multiple batches of data that are generated from different processing or reagent batches, experimenters, protocols, or profiling platforms.

Using next-generation sequencing technology to measure gene expression, an empirically intriguing question concerns the identification of differentially expressed genes across treatment groups. Existing methods aim to identify genes whose mean expressions differ among treatment groups by assuming equal dispersion across all groups.

We introduce a new method for disambiguating word senses that exploits a nonlinear Kernel Principal Component Analysis (KPCA) technique to achieve accuracy superior to the best published individual models. We present empirical results demonstrating significantly better accuracy compared to the state-of-the-art achieved by either na¨ve Bayes ı or maximum entropy models, on Senseval-2 data. We also contrast against another type of kernel method, the support vector machine (SVM) model, and show that our KPCA-based model outperforms the SVM-based model. ...

Recent approaches to text classication have used two dierent rst-order probabilistic models for classication, both of which make the naive Bayes assumption. Some use a multi-variate Bernoulli model, that is, a Bayesian Network with no dependencies between words and binary word features (e.g. Larkey and Croft 1996; Koller and Sahami 1997). Others use a multinomial model, that is, a uni-gram language model with integer word counts (e.g. Lewis and Gale 1994; Mitchell 1997).

The lake ecosystem of Hanoi has a very important role. However, the water quality in the lakes of Hanoi is declining; they're more and more polluted. Among that, eutrophication is the most popular one. Therefore, the assessment and prediction of eutrophication is necessary. One of the effective tools for assessing and predicting eutrophycation is the use of mathematical models. In this paper, we used the Vollenweider model, empirical watershed model and Jorgensen model to determine the eutrophycation of Bay Mau Lake by phosphorous concentration in the lake water.

The Aqua Augusta, an aqueduct built by Octavian (63 BC–AD 14; later known as Augustus, the first emperor of the Roman Empire), was completed in the late first century BC and provided an uninterrupted supply of pressurized water to eight towns around the bay, including Pompeii. The arrival of a constant source of running water in these cities allowed residents to design and grow more elaborate gardens. Gardeners were able to accentuate their landscape designs with springs, water courses, pools, and fountains modeled after Greek statuary.

The mutual fund data come from the 1998 CRSP Survivor Bias FreeMutual Fund Database. Our initial sample contains 2,609 domestic equity mutual funds. We exclude multiple share classes for the same fund as well as funds with only a year or less of available returns. The initial sample is used to obtain the values of the prior parameters in the empirical Bayes pro- cedure mentioned previously.
