For the Swedish data, a two step analysis was performed, in order to capture fatalities and injuries in relation to school transport crashes recorded in the national database of police reported crashes (VITS), since there is no such available adequate and compiled data.
Thus, we performed a "two steps" analysis procedure as follows.
On empirical data, our rate estimation requires a two steps analysis: 1) sampling a posterior distribution of dated phylogenies using a Bayesian molecular clock approach, and 2) estimating posterior diversification rates on these trees.
A three step numerical analysis was conducted to model flow distribution, temperature variation, and photovoltaic yield for a PV/T collector of various design (manifold sizes), geometric shape (aspect ratio), and operating characteristics (mass flow rate and flow direction in manifolds) in order to vary flow uniformity within the collector.
The novelty of this project centers on the application of a distinct two step analysis of outcomes to expedite the identification of agents suitable for Phase III testing in patients with a rare glomerular disease, namely treatment-resistant FSGS.
Content analysis was performed in three steps – analysis of the interviews, analysis of the questionnaires, and a comparison of the results.
To model thresholds simultaneously and account for their correlation, we used a three step multivariate meta-analysis approach which extends that used by Reitsma et al. 32 This three step approach was as follows.
Fairclough (2003) described a three step process when undertaking discourse analysis.
A four step kinetic analysis was applied using differential scanning calorimetry (DSC) data.
Using a Two Step Cluster analysis classification, and by means of Bayesian Schwarz's Criterion Clustering, two clusters were formed by grouping participants with similar responses.
