Unsupervised clustering represents one of the most widely applied methods in analysis of highthroughput ‘omics data. A variety of unsupervised model-based or parametric clustering methods and nonparametric clustering methods have been proposed for RNA-seq count data, most of which perform well for l[r]

Histologically similar tumors even from the same anatomical position may still show high variability at molecular level hindering analysis of genome-wide data. Leveling the analysis to a gene regulatory network instead of focusing on single genes has been suggested to overcome the heterogeneity issu[r]

Normalization is essential to ensure accurate analysis and proper interpretation of sequencing data, and chromosome conformation capture data such as Hi-C have particular challenges. Although several methods have been proposed, the most widely used type of normalization of Hi-C data usually casts es[r]

This data set which is known as Compaq data set, consists of more than 13000 images. The images are divided into two sets, about 9000 images without any skin region and about 4500 images which contains skin regions. For each of the images with skin regions, the skin[r]

To illustrate this, I have done a simulation. I used the PM 10 -data from Chicago from 1988 to 1993, to reflect the true serial correlation that is found in such data. I then assumed a true distributed lag between exposure and the log-relative-risk of death that was highest in th[r]

(BQ) Part 2 book Statistics The art and science of learning from data has contents: Statistical inference confidence intervals; comparing two groups, multiple regression, nonparametric statistics, comparing groups analysis of variance methods,...and other contents.

Data analysis methods are usually subdivided in two distinct classes: There are methods for prediction and there are methods for exploration. In practice, however, there often is a need to learn from the data in both ways.

Another variation is the so-called Crout reduction. This method is
applicable if the rows and columns are so arranged that no column inter- changes are required in the Gaussian elimination (as in the case of sym-
metric, positive definite matrices; see Theorem 3.3). Thus, in general, the[r]
