A previous study also found moderate levels of reproducibility during a two year interval (from 1989 through 1991), with a two year test-retest correlation of 0.59.
For example in a two year test on geopolitical questions, a prediction market performed 40% better than simple averages (Twardy et al., 2014).
This paper documents a five year testing program that identified factors affecting the aerodynamic drag (Fd) of alpine skiers.
We have performed a three year testing of the improved curriculum at the pilot upper primary school.
The fleet had clocked up almost a million miles over a six year testing period at that point, so has likely added a further 200,000 miles or so since then — assuming rates of testing remained the same.
Herd size and bringing animals in from high risk areas were risk factors in all four models, whilst bringing in animals from Ireland was a risk factor in four year testing areas, but not in other testing areas due, in part to the low numbers moving into 1, 2 and 3 year testing areas (Table 3).
First, we calculated inter-test intervals among patients whose previous test(s) was/were non-reactive or who had only non-acute reactive tests for a period of at least two years; tests for differences in inter-test intervals were carried out using linear regression with GEE to account for repeated measures person among those who tested three or more times.
Through the PPTCT programme, Haddeshah received vital medication and did three required blood tests over a two year period.
He tinkered with an island-settling game for four years, testing versions on his wife and children every weekend.
Recently, New York Governor Cuomo and the New York City transit agency, MTA, announced a three year pilot program to test a mere 10 electric buses.
Over a four year period, six phases of testing were performed to observe the influence of age at loading, applied stress level, mix composition and relative humidity on the tensile creep of concrete.
