WebInterpretation. Use the linear discriminant function for groups to determine how the predictor variables differentiate between the groups. For example, when you have three groups, Minitab estimates a function for discriminating between the following groups: Group 1 and groups 2 and 3. Group 2 and groups 1 and 3. WebMar 31, 2004 · The three discriminant functions are discussed below:. 1. The first function derived from the discriminant analysis accounts for much of the between group difference, explaining 54.7% of the variance, with 16 variables having significant loadings on the function. The function may be interpreted as one which differentiates between places …

WebDiscriminant analysis (DA) is a multivariate technique used to separate two or more groups of observations (individuals) based on variables measured on each experimental unit (sample) and find the contribution of each variable in separating the groups. DA works by finding one or more linear combinations of the selected variables.

WebWe can divide the process of Linear Discriminant Analysis into 5 steps as follows: Step 1 - Computing the within-class and between-class scatter matrices. Step 2 - Computing the eigenvectors and their corresponding eigenvalues for the scatter matrices. Step 3 - Sorting the eigenvalues and selecting the top k.
