Correspondence Analysis and Related Methods Session organizers: Patrick Groenen, Michael Greenacre and Jörg BlasiusDuring the last decades there has been a steady and increasing interest in correspondence analysis for the visualization and interpretation of categorical data. We hereby announce a call for papers for the IFSC2009 in Dresden on "Correspondence Analysis and Related Methods".

Four years later in 2003, we had our fourth in the series of "Cologne conferences", this time at the Universitat Pompeu Fabra in Barcelona. We decided to return to our original topic of correspondence analysis, but keeping the door open to "related methods" to foster the continuing debate on visualization of complex multivariate data, hence the conference was called "Correspondence Analysis and Related Methods", or simply CARME. This time we received 180 participants, again from all continents, who presented 82 papers and 6 posters. Again, we decided to edit a book, this time we changed the title slightly to focus on "Multiple Correspondence Analysis and Related Methods". Having finalized this manuscript, 15 years after our first conference and a huge amount of travelling between Barcelona and Cologne/Bonn, we thought that there is need for a homepage that is dedicated to "CARME" and its network "CARME-N".
Description:The authors' intention is to present multivariate data analysis in a way that is understandable to non-mathematicians and practitioners who are confronted by statistical data analysis. The book has a friendly yet rigorous style. All methods are demonstrated through numerous real examples. Mathematical results are clearly stated.
Throughout the SPSS Survival Manual you will see examples of research that is taken from a number of different data files, survey.zip, error.zip, experim.zip, depress.zip, sleep.zip and staffsurvey.zip. To use these files, which are available here, you will need to download them to your hard drive or memory stick. Once downloaded you'll need to unzip the files. To do this, right click on the downloaded zip file and select 'extract all' from the menu. You can then open them within SPSS.
MetaboAnalyst is a comprehensive platform dedicated for metabolomics data analysis via user-friendly, web-based interface. Over the past decade, MetaboAnalyst has evolved to become the most widely used platform (>300,000 users) in the metabolomics community. The current MetaboAnalyst (V5.0) supports raw MS spectra processing, comprehensive data normalization, statistical analysis, functional analysis, meta-analysis as well as integrative analysis with other omics data. The objective is to enable high-throughput analysis for both targeted and untargeted metabolomics, and to narrow the gap from raw spectra to biological insights.
A wide array of commonly used statistical and machine learning methods are available: univariate - fold change, t-test, volcano plot, ANOVA, correlation analysis; advanced feature selection - significance analysis of microarrays (and metabolites) (SAM) and empirical Bayesian analysis of microarrays (and metabolites) (EBAM); multivariate - principal component analysis (PCA), partial least squares-discriminant analysis (PLS-DA) and orthogonal partial least squares-discriminant analysis (OPLS-DA); clustering - dendrogram, heatmap, K-means, and self organizing map (SOM); as well as supervised classification - random forests and support vector machine (SVM).
MetaboAnalyst now allows users to visualize and compute associations between phenotypes and metabolomics features with considerations of other experimental factors / covariates. It employs general linear models to accommodate modern epidemiological study, together with PCA and heatmaps for visual explorations. For two-factors / time-series data, users have more options including two-way ANOVA, multivariate empirical Bayes time-series analysis (MEBA), and ANOVA-simultaneous component analysis (ASCA).
MetaboAnalyst provides the receiver operating characteristic (ROC) curve based approach for identifying potential biomarkers and evaluating their performance. It offers classical univariate ROC curve analysis as well as more modern multivariate ROC curve analysis based on PLS-DA, SVM or Random Forests. In addition, users can manually select biomarkers or set up hold-out samples for flexible evaluation and validation.
Users can upload several annotated metabolomics data sets collected under comparable conditions to identify robust biomarkers (compounds or annotated peaks) across multiple studies. It currently supports several meta-analysis methods based on p-value combination, vote counts and direct merging. The results can be explored in an interactive Upset diagram.
This module supports functional analysis of untargeted metabolomics data generated from high-resolution mass spectrometry (HRMS) such as LC-HRMS or FI-HRMS. The basic assumption is that putative annotation at individual compound level can enable more accurate functional analysis at pathway level. This is because pathway-level changes rely on "collective behavior" which is more tolerant to random errors during compound annotation (Li et al. 2013).
With MetaboAnalyst, users can now perform meta-analysis of untargeted metabolomics data. Our method extends the MS Peaks to Paths workflow to reduce the bias individual studies may carry towards specific sample processing protocols or LC-MS instruments. The current workflow allows users to perform meta-analysis of MS peaks to help identify consistent functional signatures by integrating functional profiles from independent studies or by pooling peaks from complementary instruments.
Upon completion of your analysis, a comprehensive PDF report will be generated documenting each step performed along with corresponding tabular and graphical results. All processed data and images are also freely available for download.
(5) The entries under the "Notes" column show any one of a number of things: the type of analysis for which the data set is useful, a homework assignment (past or present), or a .sas file giving the code for a SAS PROC using the data set.
Write your data analysis plan; specify specific statistics to address the research questions, the assumptions of the statistics, and justify why they are the appropriate statistics; provide references
The scripts listed below assume that data have been downloaded and stored in the working directory. Before running any of the other analysis programs, the first script listed (Set Up Variables) should be run to set up R data files.
Two sample data sets are provided here to illustrate the analysis methods described in this module. The first data set was collected by U.S. Environmental Protection Agency's Environmental Management and Assessment Program-Western Pilot Project (EMAP-West) from 2000 to 2002, and the second data set was collected in western Oregon by the Oregon Department of Environmental Quality (DEQ) from 1999 to 2000 (Figures 22 and 23). Both organizations used a similar sampling protocol. A reach 40 times the wetted width of the stream was delineated for sampling. Stream temperature was measured at the time of sampling. Substrate composition was estimated by summarizing the size distribution of particles at five locations on 21 transects. For the EMAP-West, macroinvertebrate samples were collected at eight randomized locations in riffles using a modified D-frame kicknet (500 µm mesh) by disturbing a 1 ft area for 30 seconds. In Oregon, samples were collected by disturbing 2 ft areas at four randomized locations. Samples from both studies were composited and spread on a gridded pan and picked from randomly selected grid squares until at least 500 organisms were collected. Each organism was then identified to the lowest possible taxonomic level (usually genus or species). 2ff7e9595c
