Facebook may be able to calculate the likelihood of my voting on the left side of the spectrum, but its model is crude, correlative.
When a new category bursts out — the VCR, the MP3 player, the netbook — the first models are crude, expensive and underpowered.
The early models were crude, with some snags and glitches, but she soon evolved a totally comfortable, predictable system, capable of administering a "hug" with whatever parameters she desired.
Because current climate models are "crude, it's very important that we get this right" by incorporating factors like circadian rhythms when trying to understand how the atmosphere has changed over centuries.
Accommodating patient variation through measured variables only is crude: models ought to reflect the uncertainty associated with patient casemix characteristics.
Model 1 was crude, without adjustment, model 2 was adjusted for age and BMI, and model 3 was adjusted for age, BMI, hypertension, DM, hypertriglyceridemia, and low HDL cholesterol.
Given that the native resolution of climate models is relatively crude, the accuracy of climate data resampled to a high spatial resolution is questionable [63].
This part of the model is a crude approximation of the internal pathway architecture.
Note that while the first point might simply indicate our model is too crude, the last two points suggest that this may be a real biological property rather than a modeling artifact.
Anyhow, it is remarkable that even thought this model is a crude representation of whole metabolism, and metabolism is also a limited part of all cellular phenomena, those constraints seem to be relevant enough to result in reasonably accurate predictions.
