  • 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

  • (BQ) This paper presents an investigation of the effects of machining variables on the surface roughness of wire-EDMed DC53 die steel. In this study, the machining variables investigated were pulse-peak current, pulse-on time, pulse-off time, and wire tension. Analysis of variance (ANOVA) technique was used to find out the variables affecting the surface roughness. Assumptions of ANOVA were discussed and carefully examined using analysis of residuals. Quantitative testing methods on residual analysis were used in place of the typical qualitative testing techniques.

  • In panel data models (as in single-equation multiple-regression 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 straight-forward 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.

  • This paper investigates the relationship between non-farm employment and household income in Hanoi's periurban areas. The findings showed that the vast majority of the sample households participate in non-farm activities and income from these sources mainly contributes to total household income. Factors affecting household income were examined using multiple regression models and the findings confirm the important role of non-farm employment in improving household income.

  • 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 number-giving correlates with the speed of the user’s initial response and with the user’s speaking rate.
