mcad


The aim of the experiment was to ascertain novel biomarkers of 
MCAD (Medium chain acyl-CoA dehydrogenase) deficiency. 
The data consists of 25 patients and 25 controls and the analysis was done by LC-MS.
Rows represent patients and controls and columns represent chemical 
entities with their quantity.


data

Methods for analysis of compositional data including robust
methods, imputation, methods to replace rounded zeros, (robust) outlier
detection for compositional data, (robust) principal component analysis for
compositional data, (robust) factor analysis for compositional data, (robust)
discriminant analysis for compositional data (Fisher rule), robust regression
with compositional predictors and (robust) Anderson-Darling normality tests for
compositional data as well as popular log-ratio transformations (addLR, cenLR,
isomLR, and their inverse transformations). In addition, visualisation and
diagnostic tools are implemented as well as high and low-level plot functions
for the ternary diagram.
