The Design Structure Matrix (DSM)

In statistics and in particular in regression analysis, a design matrix, also known as model matrix or regressor matrix and often denoted by X, is a matrix of values of explanatory variables of a set of objects. Each row represents an individual object, with the successive columns corresponding to the variables and their specific values for that object. The design matrix is used in certain statistical models, e.g., the general linear model. It can contain indicator variables (ones and zeros) that ind… WebJun 25, 2024 · So, this is the only implication of the rank of the dataset (or design matrix) has on the machine learning algorithm that I am aware of and comes to my mind right now, but it's possible that the rank can play other roles.
