Sentence examples for tests of the coefficients from inspiring English sources

Cox proportional hazards models were used to estimate hazard ratios and Wald tests of the coefficients from these models were used to assess statistical significance of the variables.

In contrast, the joint test of the coefficients on the post-policy dummy and post-policy × market structure interaction gives a p-value of 0.447.

As shown in the table, the fitting effects of the quadratic and cubic regressions are imperfect, and the t-test of the coefficients is insignificant.

In this case, a test of the coefficients for the treatment-day interaction equaling zero is equivalent to a test of the treatment effect at Day 7 and Day 14.

To overcome the multiple testing problem while testing which of the coefficients are nonzero, we controlled the false discovery rate (FDR) using the R package fdrtool and computed the FDR q value for each regression coefficient (Strimmer 2008).

Differences between regression coefficients of two task conditions were tested by performing linear hypothesis tests of the regression coefficients (F tests) using linhyptest in MATLAB.

The t-test of the coefficient indicates if the difference-in-difference estimate is statistically significant.

The relative importance of prognostic factors was measured by the chi-square values, based on the Wald test of the coefficient associated with each prognostic factor in the Cox model (Marubini and Valsecchi, 1995).
