In addition to the primary specification, I estimate models including shared individual and firm frailties, models comparing voluntary vs. involuntary separations, and models with alternative hazard specifications.
The primary specification is that the "objective is not only to acquire knowledge" but also to contribute "to the solution of a concrete practical problem" (ibid).
Designing in this way raises the level of abstraction of the primary specification, allowing designers to explore the architectural trade-offs and hardware/software partition decisions that need to be made at a higher level.
Given the very low yields and the resulting limitations to accurate measurement of extracted RNA for many samples, acceptance criteria for the assay include a specification of the average of the reference genes rather than on mass of RNA input as the primary specification for sample quality.
This article reviews the critical components of sample size calculation, including the selection of a primary outcome, specification of the acceptable types I and II error rates, identification of the minimal clinically important difference, and estimation of the error associated with measuring the primary outcome.
Furthermore, the Sun1 −/−Sun2 +/− Purkinje cells exhibited retarded primary dendrite specification, reduced dendritic complexity and aberrant patterning of synapses.
AR publications rarely report the use of eligibility criteria, randomization, allocation concealment, blinding, sample size calculation, primary outcome specification, and study replication [ 6- 13, 14] 14].
Therefore, it would be not surprising if compromising the link between the nucleoskeleton and cytoskeleton through the LINC complex results in retarded primary dendrite specification (Fig. 6A,B).
Here, we report our findings on the selective defect in the nuclear positioning and primary dendrite specification of Sun-deficient Purkinje cells, which resulted in ataxia-producing cerebellar dysmorphogenesis.
