WebbY = Xβ + e. Where: Y is a vector containing all the values from the dependent variables. X is a matrix where each column is all of the values for a given independent variable. e is a vector of residuals. Then we say that a predicted point is Yhat = Xβ, and using matrix algebra we get to β = (X'X)^ (-1) (X'Y) Comment. Webb16 apr. 2013 · Linear regression can be used to predict values of one variable, given the values of other variables. For inference from linear regression to be valid, the data must satisfy certain assumptions. Testing that the data satisfy these assumptions is a vital part of the analysis.
