The gram method is a linear algebra technique that is used to find solutions to systems of linear equations. There are several synonyms for the gram method, including the orthogonal projection method, the least squares method, and the normal equation method. These methods all share the same goal of finding the best fit line or plane to a set of data points. The gram method specifically involves finding the coefficients of a linear equation by projecting the data points onto a vector space and minimizing the distance between the data points and the linear equation. Regardless of the specific technique used, these methods are essential tools in various fields of study, including statistics, engineering, and physics.
