The phrase "a sample of field" is not correct in standard written English.
It may be intended to refer to a sample taken from a specific field or area of study, but it lacks clarity and proper structure.
Example: "We collected a sample of the field data to analyze the soil composition."
Alternatives: "a sample from the field" or "a field sample".
This illustrative example is a first attempt to implement an attention-corrected choice model with a sample of field data from a conjoint choice experiment.
In [18], carbon stocks were estimated with 1-ha resolution at the national scale of Panama, based on a sample of field plots and ALS in combination with full areal coverage of Landsat and MODIS data.

Postrace urine tests are made of winning horses and a sample of the field, and if results show the presence of forbidden substances, the results may be changed on payment of purses but not on bets.
A sample of 160 field plots was selected from the population and measured, and auxiliary datasets from Landsat 8 were acquired.
A previous Sanger-based re-sequencing study identified 494 SNPs from 20.5 kilobases of sequence (71.4% coding, with 303 SNPs mapping to the coding region), derived from a sample of 21 field and colonized specimens of An. funestus [49].
Such models are firstly calibrated on a sample of corresponding field- and ALS observations, and then used to predict AGB over the entire area covered by ALS data.
Here we develop and test a method for estimating in-season crop acreage using a probability sample of field visits and producing wall-to-wall crop type maps at national scales.
Variables of interest such as biomass or carbon stock are assessed on a small sample of field plots, and these data are combined with the more densely-sampled earth observation data using statistical estimation procedures in order to generate estimates.
The approach combines an ingrowth core, which is commonly used to measure fine-root production in forest topsoil, with an outer casing that facilitates the retention of a sample representative of field conditions, and a laboratory protocol that enables extrusion and measurement of biomass at different depth increments.
Sampling was undertaken in 32 10 × 10 km squares throughout England, each containing a sample of the different field margin types.
