  "term": "Multilinear least squares regression",
  "field": "Chemistry",
  "definition": "A statistical method used to model the relationship between a dependent variable and two or more independent variables by fitting a linear equation to observed data. It minimizes the sum of the squares of the residuals, which are the differences between observed and predicted values. This technique is a fundamental tool in multivariate calibration for quantitative analysis.",
