In particular, we will provide outputs from SPSS in which we obtain bootstrap confidence intervals for parameter estimates as a means of supporting significance testing of model parameters. The subjects are males engaged in sedentary occupations. The multiple correlation coefficient is the square root of the coefficient of multiple determination and, consequently, the sample value may be computed by taking the square root of Equation Educational and Psychological Measurement, 45 1 Bootstrap confidence intervals for each parameter estimate are shown in Figure Test statistic. The closer the coefficient is tothe stronger the evidence of a significant linear relationship between and. A Coefficient of Agreement for Nominal Scales. Lima: Autor. These adjustments are sometimes called family-wise error rates, and can be found in many computer software packages. The SPSS statistical software package for the PC provides a convenient procedure for obtaining partial correlation coefficients.
