ERV3 is thought to be originated more than 30 million years ago [17], an assumption verified by our results that place the ERV3 integration around 42 million years ago.
This model is based on the physics of semi-conductor and is simplified according to some assumptions verified through experimental results and/or numerical simulations.
The linearity assumption was verified using the runs test, and scatter and residual plots were used to verify model assumptions.
The normality assumption was verified using the Shapiro-Wilk's statistic while the homogeneity of variances was verified graphically with the residuals plot.
and the assumption is verified.
The validity of this assumption is verified later through simulations in Section 5.
The proportional hazards assumption was verified using the Schoenfeld residuals method.
as for Hence, we can choose sufficiently large such that, and Assumption is verified.
The normality assumption was verified via the shape of the histogram of the test values.
Proportionality of hazard assumption was verified in all models.
