Regression tool included with Analysis ToolPakД«elow you will find the detailed instructions on using each method.

The three main methods to perform linear regression analysis in Excel are: There exist a handful of different ways to find a and b. Mathematically, a linear regression is defined by this equation:ДЇor our example, the linear regression equation takes the following shape: Plot this information on a chart, and the regression line will demonstrate the relationship between the independent variable (rainfall) and dependent variable (umbrella sales): The focus of this tutorial will be on a simple linear regression.ДЄs an example, let's take sales numbers for umbrellas for the last 24 months and find out the average monthly rainfall for the same period. If the dependent variable is modeled as a non-linear function because the data relationships do not follow a straight line, use nonlinear regression instead. If you use two or more explanatory variables to predict the dependent variable, you deal with multiple linear regression. Simple linear regression models the relationship between a dependent variable and one independent variables using a linear function. In statistics, they differentiate between a simple and multiple linear regression. The goal of a model is to get the smallest possible sum of squares and draw a line that comes closest to the data. Technically, a regression analysis model is based on the sum of squares, which is a mathematical way to find the dispersion of data points. Regression analysis helps you understand how the dependent variable changes when one of the independent variables varies and allows to mathematically determine which of those variables really has an impact. Independent variables (aka explanatory variables, or predictors) are the factors that might influence the dependent variable. In statistical modeling, regression analysis is used to estimate the relationships between two or more variables:Дependent variable (aka criterion variable) is the main factor you are trying to understand and predict. Regression analysis in Excel - the basics

Regression analysis in Excel with formulas.

Linear regression in Excel with Analysis ToolPak.

It will give you an answer to this and many more questions: Which factors matter and which can be ignored? How closely are these factors related to each other? And how certain can you be about the predictions? But how do you know which ones are really important? Run regression analysis in Excel. You have discovered dozens, perhaps even hundreds, of factors that can possibly affect the numbers.
