Second, if the distribution of elasticities is conditional on regional and sectoral characteristics, then segmentation of the analysis by subsets of these variables may serve to truncate the dependent variable (Koenker and Hallock 2001).
Open image in new window Fig. 3 Distribution of wage elasticity to taxes (elasticity of net wages to taxation).
Another view of the cause of orthostatic headaches proposes a malformed distribution of craniospinal elasticity as a result of the collapse of the lower spine's CSF space resulting in the collapse of the dura sac.
Similar to SE, SWE can colour-code the distribution of tissue elasticity.
Another newly implemented technique is real-time sonoelastography (RTE), which enables the illustration of distribution of tissue elasticity in one US slice.
To visualise the distribution of tissue elasticity, images are colour-coded, for example, from red (soft tissue) to blue (hard tissue).
Fig. 1 Distribution of wage elasticities by demographic group Fig. 2 Distribution of wage elasticities by demographic group and country.
Figure 1 plots the distribution of wage-elasticity estimates by demographic group.
This is confirmed in Fig. 2 (top-left quadrant) where we plot the distribution of wage-elasticity estimates for each country.
Consequently, a number of scoring systems comparing the presence, size and distribution of areas of elasticity within the greyscale ultrasound abnormality have been devised [ 6, 7].
