The most commonly used type of regression is linear regression, which looks for the relationship between the variables by attempting to fit a linear equation, or straight line, to the available data.This is the type of regression covered in this tutorial and is useful for many analysis applications. If known_data_y is a two-dimensional array or range, known_data_x must have the same dimensions or be omitted. Using Google products, like Google Docs . We have 10 regression statistics computed using the same dataset in the example below. The coefficient of determination ranges from 0 to 1 with higher numbers meaning a stronger correlation. The following examples show how to use this function in practice. In our example, we find out that the line has a slope of 1.997 and intercepts the y-axis at x=3.86. The linear regression equation is in the form 'y= a+bx'. Regression is a statistical method used to investigate the relationship between a dependent variable or variable of interest and one or more independent variables that you think may affect the dependent variable. Calculates the y-value at which a line will intersect the y-axis by using known x-values . This video covers:1.
