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:ĭependent 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.
Imagine this: you are provided with a whole lot of different data and are asked to predict next year's sales numbers for your company.

The data analysis functions can be used on only one worksheet at a time. Some tools generate charts in addition to output tables. You provide the data and parameters for each analysis, and the tool uses the appropriate statistical or engineering macro functions to calculate and display the results in an output table. If you need to develop complex statistical or engineering analyses, you can save steps and time by using the Analysis ToolPak. Solution home Microsoft Office Excel Load the Analysis ToolPak in Excel
