Simple linear regression quantifies the relationship between two variables by producing an equation for a straight line of the form y =a +βx which uses the independent variable (x) to predict the dependent variable (y). Regression involves estimating the values of the gradient (β)and intercept (a) of the line that best fits the data . This is defined
The constant term in linear regression analysis seems to be such a simple thing. Also known as the y intercept, it is simply the value at which the fitted line crosses the y-axis. While the concept is simple, I’ve seen a lot of confusion about interpreting the constant.

Linear Regression is a simple machine learning model for regression problems, i.e., when the target variable is a real value. Linear regression is a linear model, e.g. a model that assumes a linear relationship between the input variables (x) and the single output variable (y).
Instead of using the EXCEL regression program to fit a line to the data we will now use an alternative least squares method to do the same job. There are four steps to this method; Step1. Define or get a linear data set as in previous examples. We will call the data data(t) Step2. Define a model that we want to fit to the data.
Excel's regression functions let you perform regression analysis. In a nutshell, regression analysis involves plotting pairs of independent and dependent variables in an XY chart and then finding a linear or exponential equation that describes the plotted data.
Doing a Linear Regression Analysis, Using Excel (version from Office '97) There are actually two ways to do a linear regression analysis using Excel. The first is done using the Tools menu, and results in a tabular output that contains the relevant information.
This article explains how to apply employee engagement analytics. Most companies collect employee engagement data. This data will only add value to business goals when analyzed. This article describes the process of defining, measuring, and developing (semi-automated) employee engagement analytics.
