Figures 5, 6 and 7 represent the results obtained from applying the linear ordinary least squares regression statistical technique (p-value and correlation coefficient r) between the value of the outsourcing index (OT, Table 4) and the value of the variables / invoicing, representing the significant variables and their relation with the variable of outsourcing, (all variables are included in Table A.
Ordinary least squares regression yielded a standardized number for each variable, the beta coefficient, that was convenient to use in comparing the effects of variables and in clustering decision-making policies.
Quantile regressions are very different from ordinary least squares regression and is best explained by analogy: regular ordinary least squares summarizes how the mean value of the dependent variable varies with some X regressor, whereas quantile regressions summarize how some quantiles (that is, median or 10th percentile) of the dependent variable vary with some X regressor.
The ordinary least squares regression using JOINT in place of the five factors is reported in column three of Table II.
2) A multiple regression model was developed and ordinary least squares regression was employed to estimate the effect of the letter intervention in both the long-term care and ambulatory patient populations.
Logistic regression was chosen in preference to ordinary least squares regression because it is appropriate for a dichotomous dependent variable.
Loss severity, on the other hand, is a continuous variable referring to the amount on a percentage basis of loss experienced by the defaulted loan and is modeled by ordinary least squares regression.
The discussion is limited to (1) the analysis of data by the analytic procedures of ordinary least squares regression, discriminant analysis, or logistic regression; (2) the use of the Statistical Package for the Social Sciences (registered) computer software; and (3) a dependent variable consisting of two groups.
The model was estimated both with maximum likelihood and with ordinary least squares regression methods.
Ordinary least squares regression was used to build two annual earnings models--one for the subsample that was primarily in the workforce (the W population) and the other for the sample that was primarily in postsecondary education (the PSE population).
Ayanian studies the Fed real exchange rate index for the period 1973-85 (on an annual basis) as the independent variable of a simple ordinary least squares regression.
