A method of analysis of incomplete data sets to detect fraudulent data is disclosed. The method comprises computing constant values for various leading digit sequence lengths, computing artificial Benford frequencies for the digit sequence lengths, computing a standard deviation for each of the sequence...

STATIS is a three-way method for exploratory data analysis. It is best understood starting from an unfolded two-way table. For an I×J×K data set this is obtained by juxtaposition of K (I×J) two-way tables. To analyze the resulting table by PCA, the variance–covariance matrix is us...
The method comprises aggregating related data tables with dissimilar data structures, and combining the tables, and data structures, into a single table that incorporates all the individual data structures. The single table is then analyzed via a pivot table function of a spreadsheet program, such ...
Time shift among samples remains a significant challenge in data analysis, such as quality control of natural plant extracts and metabolic profiling analysis, because this phenomenon may lead to invalid conclusions. In this work, we propose a new time shift alignment method, namely, automatic time-...
A GPU accelerated interactive interface for exploratory functional connectivity analysis of FMRI data Functional connectivity analysis is a way to investigate how different parts of the brain are connected and interact. A common measure of connectivity is t... A Eklund,O Friman,MT Andersson,... -...

The read_fwf method is used to read data from fixed width files, where every field is in the same place in every line. The default usage will be to read the data in text format in the R workspace. The code for this is shown as follows: read_fwf("data.txt") Here, readr will try...
TheReporterScorepackage has built-in KEGG pathway, module, gene, compound, and GO databases and also allows customized databases, making it compatible with feature abundance tables from diverse omics data. You can choose any of the following methods to load the database based on your analysis nee...
