Let (x 1,y 1), (x 2,y 2)(x n,y n) is a given data set, representing pairs of certain variables; where x denotes independent (explanatory) variable whereas y is independent variable - which values we want to estimate by a model.Conceptually the simplest regression model is that one which describes relationship of two variable assuming linear association The Linear Regression Slope is calculated using the Linear Regression theory. This actually notes the rate of change of the regression line per bar. This is also a lagging indicator and generates signals on the basis of zero line cross. We can use it with other indicators or some other oscillators to fine tune the exact entry and exit points For our interactive calculator, we will be performing simple linear regression where we attempt to model the relationship between one input variable and one output variable. This is opposed to multiple linear regression that models the relationship between two or more input variables (explanatory) and one output variable (the response) Linear regression models are the most basic types of statistical techniques and widely used predictive analysis. They show a relationship between two variables with a linear algorithm and equation. Linear regression modeling and formula have a range of applications in the business Regression equation. By default the option Include constant in equation is selected. This is the recommended option that will result in ordinary least-squares regression. When you need regression through the origin (no constant a in the equation), you can uncheck this option (an example of when this is appropriate is given in Eisenhauer, 2003)

Linear Regression Line --- a ³best fitting² line for a certain group of data that have been plotted. This allows you to make predictions about where other points would most likely fall Simple linear regression is an approach for predicting a response using a single feature. It is assumed that the two variables are linearly related. Hence, we try to find a linear function that predicts the response value(y) as accurately as possible as a function of the feature or independent variable(x) Linear regression equations. If we expect a set of data to have a linear correlation, it is not necessary for us to plot the data in order to determine the constants m (slope) and b (y-intercept) of the equation .Instead, we can apply a statistical treatment known as linear regression to the data and determine these constants.. Regression equations are frequently used by scientists, engineers, and other professionals to predict a result given an input. These equations have many applications and can be developed with relative ease. In this article I show you how easy it is to create a simple linear regression equation from a small set of data
