También puede utilizar las funciones de MATLAB polyfit y polyval para ajustar sus datos a un modelo lineal en los coeficientes. Para ver un ejemplo, consulte Ajuste programático . Si necesita ajustar los datos con un modelo no lineal, transforme las variables para que la relación sea lineal.

Matlab offers an easier method for fitting linear models -- the fitlm function. To use MATLAB, Statistics, and Linear Regression. Justin Werfel The basic MATLAB data type is a matrix, an array of values (by default, double- precision floating Linear regression is one of the fundamental models in statistics used to determine the rela- tionship between dependent and independent variables.

Each row of the input data represents one observation. I just want to fit to a very simple equation, i.e. y = kx + b. Is that possible in MatLab? I need the slope, intercept and R-squared.
