The phrase "attack the model" is correct and usable in written English.
It can be used in contexts such as discussing critiques, evaluations, or challenges to a theoretical framework or computational model.
Example: "In our analysis, we decided to attack the model by testing its assumptions against real-world data."
Alternatives: "challenge the model" or "critique the model".
Birds also took a relatively longer time to attack the model with a pair of eyespots.
Kirk correctly but belatedly guesses that there will be a follow-up attack — the model is the second I.E.D. that takes out the first responders, a sequence we've seen often in the past few years — and watches his mentor die.
In the second test (1 vs 5 eyespots per wing, where the area of each eyespot in the latter treatment was reduced such that the total eyespot size was equal in both treatments), birds preferred to first attack the model with 5 eyespots (Binomial Test: N = 93; P = 0.0220)., taking significantly lesser time to attack the one with 5 eyespots (Wilcoxon signed-rank test: V = 2716; P = 0.0422; N = 93).
Birds attacked models with a single eyespot significantly more than those with a pair of eyespots (N = 75; P = 0.0052)., taking a longer time to attack the models with a pair of patterns (V = 1877; P = 0.0170; N = 75).
Birds mostly avoided the model that looked like the local frog, but they attacked the model that looked like the frog from the other site, Chouteau reports in the December issue of The American Naturalist.
The latency was significantly higher only when the birds attacked the model with 1 eyespot/hindwing after attacking model with none (Mann–Whitney U Test: W = 942, P = 0.0276).
In the first test, birds that preferred to attack the eyespot-less model first, attacked the second model (with 1 eyespot per wing) after a significantly longer time than birds that attacked the models in a reverse order (Mann–Whitney U Test: W = 942, P = 0.0276).
The remaining tests (all comparing models with conspicuous patterns) demonstrated no significant differences in latency to attack the second model (Additional file 1: Figure S2).
To compare the latency to attack the second model after the first, a Mann–Whitney U Test was performed.
Brailsford attacked the "mathematical model" as "only an estimation" and says it is not possible to prove his riders are drug free.
But the city and medallion stakeholders have a lot to lose -- in fact, the city of Chicago and the state of Illinois have attacked the ridesharing model.
