Mechanical testing of the joints revealed that the minimum tensile strength matched the ultimate tensile strength of the weakest material, Niobium.
"Statistical tests of the joint distribution of spectral acceleration values," Bulletin of the Seismological Society of America, 98 (5), 2231-2243.
The static bending tests of the beams were performed for the optimum fiber stacking sequence, followed by the static tensile tests of the joint between the composite beam and the brackets on the car body.
A test of the joint null hypothesis of parameter stability and a unit root within an ADF style autoregressive specification whose entire parameter structure is potentially subject to a structural break at an unknown time period is developed.
Table 4 presents joint tests of the joint significance and impact of the three human capital measures.
The lower p-value corresponds to a LR test of the joint significance of all the regressors after matching.
We also ran a formal test of the joint null hypothesis that α i = β i for i = 0,…,5.
P-value-chi2 is the p-value of the likelihood-ratio test of the joint insignificance of all the regressors before and after matching.
The first row shows a linear F-test of the joint significance of the macro variables on their association with the legislated tax shocks.
The upper p-value corresponds to a likelihood-ratio (LR) test of the joint significance of all the regressors before matching.
