Multiple regression

Multiple regression is the extension of simple regression, to take account of more than one independent variable X. In multiple regression, we study the relationship between Y and a number of explanatory variable (X1, X2, …, Xk). The model we assume is as follows: Yi = β0 + β1X1 + β2X2 + … + βkXk + ei

This book had its origin over 30 years ago, when it became apparent to Jack Cohen that there were relationships between multiple regression and correlation (MRC) on the one hand and the analysis of variance (ANOVA) on the other which were undreamed of (or at least did not appear) in the standard textbooks with which he was familiar. On the contrary, the texts of the era treated MRC and ANOVA as wholly distinct systems of data analysis intended for types of research that differed fundamentally in design, goals, and types of variables.

In panel data models (as in singleequation multipleregression models) we are interested in testing two types of hypotheses: hypotheses about the variances and covariances of the stochastic error terms and hypotheses about the regression coefficients. The general to simple procedure provides a good guide.

From the system we call the ‘normal equation system’ we can solve K normal equations for K unknown beta coefficients. The straightforward representation of the solution is expressed in the matrix algebra. However, since the main purpose is the application and EViews. Other data analysis software is available, so we can easily find regression coefficients without remembering all the algebraic expressions.

Collinearity refers to linear relationships between two X variables. Multicollinearity encompasses linear relationships between more than two X variables. Multiple regression is impossible in the presence of perfect collinearity or multicollinearity. If X1 and X2 have no independent variation, we cannot estimate the effects of X1 adjusting for X2 or vice versa. One of the variables must be dropped. This is no loss, since a perfect relationship implies perfect redundancy. Perfect multicollinearity is, however, rarely practice problem.

This short text is the output of a desire to produce a helpful additional source for my students and from that, perhaps be of use to other similar students and managers of this subject area. After several years of working with classes on Management Decision Making, the need for a short and focused integrative text was clear to me. There are many excellent texts on both the qualitative and quantitative aspects of decision making, but few which address both.

accountants probably have always been concerned with measuring and reporting the relationship between cost and output. The preeminence of fi nancial accounting in this century resulted in directing much of our attention toward attaching costs to inventories. However, the recent emphasis on decision making is causing us to consider ways of measuring the variability of cost with output and other decisions variables. In this essay, the application, use, and limitations of multiple regression analysis, a valuable tool for measuring costs, are discussed....

Today there are many services which provide information over the phone using a prerecorded or synthesized voice. These voices are invariant in speed. Humans giving information over the telephone, however, tend to adapt the speed of their presentation to suit the needs of the listener. This paper presents a preliminary model of this adaptation. In a corpus of simulated directory assistance dialogs the operator’s speed in numbergiving correlates with the speed of the user’s initial response and with the user’s speaking rate.
