Linear discriminant analysis (LDA), normal discriminant analysis (NDA), or discriminant function analysis is a generalization of Fisher's linear discriminant, a method used in statistics and other fields, to find a linear combination of features that characterizes or separates two or more classes of objects or … Se mer The original dichotomous discriminant analysis was developed by Sir Ronald Fisher in 1936. It is different from an ANOVA or MANOVA, which is used to predict one (ANOVA) or multiple (MANOVA) … Se mer Discriminant analysis works by creating one or more linear combinations of predictors, creating a new latent variable for each function. These functions are called discriminant functions. The number of functions possible is either $${\displaystyle N_{g}-1}$$ Se mer An eigenvalue in discriminant analysis is the characteristic root of each function. It is an indication of how well that function differentiates the … Se mer Some suggest the use of eigenvalues as effect size measures, however, this is generally not supported. Instead, the canonical correlation is … Se mer Consider a set of observations $${\displaystyle {\vec {x}}}$$ (also called features, attributes, variables or measurements) for each sample of an object or event with … Se mer The assumptions of discriminant analysis are the same as those for MANOVA. The analysis is quite sensitive to outliers and the size of the smallest group must be larger than the number of predictor variables. • Se mer • Maximum likelihood: Assigns $${\displaystyle x}$$ to the group that maximizes population (group) density. • Bayes Discriminant … Se mer NettetFurthermore, to improve the accuracy and precision of quantitative analysis of SERS assays with a multiplicative effects model for surface-enhanced Raman spectroscopy. Conclusion: A LOD of 20 pM DA-level was obtained, and the linear response ranged from 30 pM to 300 nM for quantitative DA detection.
