Normal equation.<\/p>\n<p>A normal equation is an equation that is obtained by multiplying each equation in a system of linear equations by the coefficient of its unknowns and then adding the equations together. The normal equations can be used to solve for the unknowns in the system of linear equations.<\/p>\n<p>An observation equation is an equation that is used to represent the relationship between a dependent variable and one or more independent variables.
