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… WebMatrix Design Group corporate office is located in 2435 Research Pkwy Ste 300, Colorado Springs, Colorado, 80920, United States and has 372 employees. matrix design group inc matrix design group matrix group inc matrix consulting group matrix environmental services llc matrix electric inc Matrix Design Group Global Presence Search All …
