The projects were developed through lengthy iterations of model-making and what she called "slimy drawings" – pre-digital, hand-crafted axonometrics that have more in common with natural history illustrations than the sleek, seamless renderings of today's parametric modelling software.
The parametric model's interface and operation workflow have been extremely simplified to reduce the learning period required for the clinician.
A screw seat was embedded in the parametric model's internal source and copied to the 4 positions on the V curves.
Operation efficiency for clinicians: In the orthosis design exercise, under the parametric model's facilitation, the required time for executing an orthosis design was dramatically reduced to a few minutes.
An informal assessment of a parametric model's appropriateness may be made via plotting the (smoothed) empirical hazard or cumulative hazard against those estimated by the model, or by log(−log(survival)) plots which are discussed later.
An illustration of the reference output y t, θ ref ) and the noisy signal y meas (t) is given in the left of Figure 4. We want to recover the values of the parameters u1 and u2 based on fitting the reduced parametric model's output ŷ (t, θ ) to the measured output y meas (t).
The assessment of robustness was based on the semi-parametric PWP model's ability to predict the successive times of occurrence of events when the underlying process actually is parametric (specifically a NHPP having log-linear proportional intensity function with one covariate).
Test-retest reliability of the CAPANS-PA questionnaire, was assessed by ICC's (one-way random model) for parametric (interval and ratio) variables with acceptable reliability defined as an ICC ≥ 0.70 [ 41].
Solve program error or software crash: Sometimes, because the immobilization area overlapped on the limb model's edge or a hole, the parametric model may generate a distorted surface, separate objects or have no response when attempting to update a model, even causing Rhino to crash.
We computed robust standard error estimates of the tobit model's regression coefficients using the non-parametric bootstrap of Efron [ 34].
