Basic Concepts & Methodology
1. Introduction
Regression analysis is by far the most popular technique in business and economics for
seeking to explain variations in some quantity in terms of variations in other quantities, or to
develop forecasts of the future based on data from the past. For example, suppose we are
interested in the monthly sales of retail outlets across the UK. An initial data analysis would
summarise the variability in terms of a mean and...

Correlation only indicates the degree and direction of relationship between two variables. It does not, necessarily connote a causeeffect relationship. Even when there are grounds to believe the causal relationship exits, correlation does not tell us which variable is the cause and which, the effect. For example, the demand for a commodity and its price will generally be found to be correlated, but the question whether demand depends on price or viceversa; will not be...

2. The model with the highest R2 might actually "overfit" the data and not provide accurate predictions. The R2 statistic can be inflated (or made arbitrarily large) by including superfluous independent variables in the model.

The Main Idea of a Multiple Regression Analysis
Introduction:
The main idea of a multiple regression analysis is to understand the relationship between several independent variables and a single dependent variable. (Lind, 2004) A model of the relationship is hypothesized, and estimates of the parameter values are used to develop an estimated regression equation.(abyss.uoregon.edu) The multiple regression equation used to describe the relationship is: Y' = a + b1X1 + b2X2 + b3X3 + . + bkXk. It is used to estimate Y given selected X values...

Executive Summary
Every portfolio has a set of delinquent customers who do not make their payments on time.
The financial institution has to undertake collection activities on these customers to recover the
amounts due. A lot of collection resources are wasted on customers who are difficult or
impossible to recover. Predictive analytics can help optimize the allocation of...

H0: The variables will predict whether or not a team will make the playoffs.
H1: The variables will not predict whether or not a team will make the playoffs.
After running the regressions, it’s clear that all of the variables are insignificant at the 5% level.
The only one that may have some significance is the rush rank, yet even that variable is not a great indicator of whether or not a team will make the playoffs.
The relationship between rush rank and making the playoffs is...

Regression Analysis of Work Hours in Relation to GPA
This research investigated the affects of working extra hours in a labor position on students’ GPAs each semester at Berea College. It was my belief that students who worked more hours were more likely to have lower GPAs due to their studying abilities and opportunities being compromised as a result of working too long (a negative correlation or trend between GPAs and hours worked each week)....

How to Analyze the Regression Analysis Output from Excel
In a simple regression model, we are trying to determine if a variable Y is linearly dependent on variable X. That is, whenever X changes, Y also changes linearly. A linear relationship is a straight line relationship. In the form of an equation, this relationship can be expressed as
Y = α + βX + e
In this equation, Y is the dependent variable, and X is the independent variable. α is the intercept of the regression line, and β is...

Multiple regression, a timehonored technique going back to

the variance in an interval dependent, based on linear
combinations of interval, dichotomous, or dummy independent
variables. Multiple regression can establish that a set of
independent variables explains a proportion of the variance in a
dependent variable at a significant level (through a significance
test of R2), and can establish the relative predictive importance...

The Ordinary Least Squares method of estimation can easily be extended to models involving two or more explanatory variables, though the algebra becomes progressively more complex. In fact, when dealing with the general regression problem with a large number of variables, we use matrix algebra, but that is beyond the scope of this course.
We illustrate the case of two explanatory variables, X1 and X2, with Y the dependant variable....

In statistics, linear regression is an approach to model the relationship between a scalar dependent variable y and one or more explanatory variables denoted X. The case of one explanatory variable is called simple linear regression. For more than one explanatory variable, it is called multiple linear regression. (This term should be distinguished from multivariate linear regression, where multiple correlated dependent variables are predicted,[citation needed] rather than a...
