Definition of Regression analysis

Regression Analysis Image 1

Regression analysis

A statistical technique that can be used to estimate relationships between variables.


Regression analysis

Statistical analysis techniques that quantify the
relationship between two or more variables. The intent is quantitative
prediction or forecasting, particularly using a small population to forecast the
behavior of a large population.

least squares regression analysis

a statistical technique that investigates the association between dependent and independent variables; it determines the line of "best fit" for a set of observations by minimizing the sum of the squares
of the vertical deviations between actual points and the
regression line; it can be used to determine the fixed and
variable portions of a mixed cost


Coefficient of determination

A measure of the goodness of fit of the relationship between the dependent and
independent variables in a regression analysis; for instance, the percentage of variation in the return of an
asset explained by the market portfolio return.


dispersion

the degree of variability or difference; it is measured
as the vertical distance of an actual point from the
estimated regression line in least squares regression analysis


method of least squares

see least squares regression analysis



Ordinary least squares (OLS)

regression analysis a statistical technique that minimizes the sum of the squared deviations between a dependent variable and one or more independent variables and provides the user
with a y-intercept and x-coefficients, as well as feedback such as R2 (explained
variation/total variation) t-statistics, p-values, etc.


Simple linear regression

A regression analysis between only two variables, one dependent and the other explanatory.

activity analysis

the process of detailing the various repetitive actions that are performed in making a product or
providing a service, classifying them as value-added and
non-value-added, and devising ways of minimizing or eliminating
non-value-added activities


BARRA's performance analysis (PERFAN)

A method developed by BARRA, a consulting firm in
Berkeley, Calif. It is commonly used by institutional investors applying performance attribution analysis to
evaluate their money managers' performances.


Break-even analysis

An analysis of the level of sales at which a project would make zero profit.


break-even analysis

analysis of the level of sales at which the company breaks even.


Break-Even Analysis

An analytical technique for studying the relationships between fixed cost, variable cost, and profits. A breakeven chart graphically depicts the nature of breakeven analysis. The breakeven point represents the volume of sales at which total costs equal total revenues (that is, profits equal zero).


capital investment analysis

Refers to various techniques and procedures
used to determine or to analyze future returns from an investment
of capital in order to evaluate the capital recovery pattern and the
periodic earnings from the investment. The two basic tools for capital
investment analysis are (1) spreadsheet models (which I strongly prefer)
and (2) mathematical equations for calculating the present value or
internal rate of return of an investment. Mathematical methods suffer
from a lack of information that the decision maker ought to consider. A
spreadsheet model supplies all the needed information and has other
advantages as well.


Cluster analysis

A statistical technique that identifies clusters of stocks whose returns are highly correlated
within each cluster and relatively uncorrelated between clusters. Cluster analysis has identified groupings
such as growth, cyclical, stable and energy stocks.


Common-base-year analysis

The representing of accounting information over multiple years as percentages
of amounts in an initial year.
Common-size analysis The representing of balance sheet items as percentages of assets and of income
statement items as percentages of sales.


Comparative credit analysis

A method of analysis in which a firm is compared to others that have a desired
target debt rating in order to infer an appropriate financial ratio target.


correlation analysis

an analytical technique that uses statistical
measures of dispersion to reveal the strength of the
relationship between variables


Cost-Benefit Analysis

The calculation and comparison of the costs and benefits of a policy or project.



cost-benefit analysis the analytical process of comparing the

relative costs and benefits that result from a specific course
of action (such as providing information or investing in a
project)


cost driver analysis

the process of investigating, quantifying,
and explaining the relationships of cost drivers and
their related costs


Cost–volume–profit analysis (CVP)

A method for understanding the relationship between revenue, cost and sales volume.


Credit analysis

The process of analyzing information on companies and bond issues in order to estimate the
ability of the issuer to live up to its future contractual obligations. Related: default risk


credit analysis

Procedure to determine the likelihood a customer will pay its bills.


Discriminant analysis

A statistical process that links the probability of default to a specified set of financial ratios.


Factor analysis

A statistical procedure that seeks to explain a certain phenomenon, such as the return on a
common stock, in terms of the behavior of a set of predictive factors.


Failure analysis

The examination of failure incidents to identify components
with poor performance profiles.


Financial Trend Analysis

Process of analyzing financial statements of a company for any continuing relationship.


First-pass regression

A time series regression to estimate the betas of securities portfolios.



Fundamental analysis

Security analysis that seeks to detect misvalued securities by an analysis of the firm's
business prospects. Research analysis often focuses on earnings, dividend prospects, expectations for future
interest rates, and risk evaluation of the firm.


Horizon analysis

An analysis of returns using total return to assess performance over some investment horizon.


Horizontal analysis

The process of dividing each expense item of a given year by the same expense item in
the base year. This allows for the exploration of changes in the relative importance of expense items over time
and the behavior of expense items as sales change.


incremental analysis

a process of evaluating changes that
focuses only on the factors that differ from one course of
action or decision to another


Linear regression

A statistical technique for fitting a straight line to a set of data points.


Mean-variance analysis

Evaluation of risky prospects based on the expected value and variance of possible outcomes.


Multiple-discriminant analysis (MDA)

Statistical technique for distinguishing between two groups on the
basis of their observed characteristics.


Multiple regression

The estimated relationship between a dependent variable and more than one explanatory variable.

a statistical technique that uses two or
more independent variables to predict a dependent variable


Pareto analysis

a method of ranking the causes of variation
in a process according to the impact on an objective
Pareto inventory analysis an analysis that separates inventory
into three groups based on annual cost-to-volume usage


Pareto analysis

The 80:20 ratio that states that 20% of the variables included in an
analysis are responsible for 80% of the results. For example, 20% of all customers
are responsible for 80% of all customer service activity, or 20% of all inventory
items comprise 80% of the inventory value.


Performance attribution analysis

The decomposition of a money manager's performance results to explain
the reasons why those results were achieved. This analysis seeks to answer the following questions: (1) What
were the major sources of added value? (2) Was short-term factor timing statistically significant? (3) Was
market timing statistically significant? And (4), Was security selection statistically significant?
