"The linear regression analysis of the relationship between two variables, X and Y. For each subject (or experimental unit), we know that X and Y, and want to find the best line through the data. In some cases the inclination and / or have intercept scientific sense. In other cases, according to the linear regression line as a standard curve, the new values of X of Y, X or Y to be found "

Define a line of the form y = mx + b to a number of data points (x_i, y_i). Hopes that the line "better" according to certain criteria. The most common is the "least squares" criteria. Take the vertical distance (called residual) for y_i x_i between and the value (m * x + b) on the line x = x i. Take the square of these distances. Myb values are found that minimize the sum of the squares of these distances to be. These parameters are as Least Squares Fit "values and the linear model y = ax + b".
This line also has the property that the average waste (no space) is zero. In a sense, not only as an error on the line like that. And it has other desirable statistical properties.
