CD Genomics is able to use OPLS-DA to help customers model the relationship between metabolite expression and sample class, thus enabling the prediction of sample class.
Orthogonal partial least squares discriminant analysis is a regression modeling method of multiple dependent variables on independent variables, which can help researchers remove data in the independent variables that are irrelevant to the categorical variables and provide researchers with simpler and easier-to-interpret models. The OPLS-DA corrects the orthogonal transformation on the basis of partial least squares analysis to filter out the noise unrelated to the categorical information and improve the resolution and validity of the model.

OPLS-DA services can be used for but are not limited to the following research:
OPLS-DA is an important tool for multi-omics studies, establishing correlations between data on histological multivariate variables and macroscopic data such as function, quality, and grade, or experimental conditions such as time and concentration, for the purposes of screening important variables, establishing evaluation criteria and examining the process.
