The program builds the inner array accordingly to fractional factorial experiments
plan and uses for the terms in array the measured values of roughness ([R.
Statistical models are developed using data of factorial experiments
that were carried out according to close to D-optimal experimental designs [B.
Based on the matrices of a full factorial experiment
on 29-30 July 2006 on the existing road with a gravel pavement two 56 and 28 meters long test sections were constructed.
A method similar to Yates have been used by Li (1944) for the construction of asymmetrical factorial experiments
4 x [2.
Experiment 4 was a fully orthogonal factorial experiment
The optimal recipes of the dispersion systems, applied as polymer matrix precursors, were determined on the basis of factorial experiments
, designed as [2.
A full factorial experiment
was performed to make sure that there is no inferred significance.
As a result, full factorial experiments
are rarely conducted with a large number of factors.
We manipulated temperature and thyroxine in 2x2 factorial experiment
, thereby testing the hypotheses that geographic variation in metamorphic timing is clue to geographic variation in (a) stream temperatures and (b) timing of thyroxine production, and/or an interaction between these two effects.
In an area adjacent to experimental plots, a factorial experiment
with two treatments, exclosures and gaps, and n = 3 replicate treatment combinations was laid out in a completely randomized design (df = 8).
Sequential experimentation seems an efficient tool to use when a large number of independent variables are to be examined simultaneously, especially when compared with the usual alternative: a single, prohibitively large factorial experiment
Similarly, the reciprocal factorial experiment
presented here confirmed a large maternal contribution to seed mass in Nemophila menziesii, but could not, in principle, reveal its basis.
