Linear least squares

Linear least squares is one of the mathematics/statistical problem solving methods, using least squares algorithmic technique to increase solution approximation accuracy, corresponding with a particular problem's complexity:

• Linear least squares (mathematics); also ordinary least squares (mathematics), or numerical methods for linear/ordinary least squares; concerning the mathematics and computational aspects of the corresponding optimisation problem
  • Linear regression, concerning the statistical context in which linear least squares often arises. Special cases are:
    • Simple linear regression or straight line regression
    • Ordinary least squares (statistics) or Linear least squares (statistics)
    • Weighted least squares
    • Generalized least squares
