The phrase "assumption of data" is correct and usable in written English.
It can be used in contexts where one is discussing the acceptance or presumption of certain data as a basis for analysis or decision-making.
Example: "The assumption of data in this study is critical for drawing accurate conclusions about the research findings."
Alternatives: "presumption of data" or "acceptance of data".
This is because a stronger unsupervised feature selection technique is needed to ignore the independent and identically distributed assumption of data.
Augmented Dickey-fuller test considering H0: series x t is I (1) against I (0) by assumption of data have dynamic structure.
The water table depth was chosen as the interpolated data instead of the height (elevation) of the groundwater table to assure the assumption of data stationarity when using the kriging technique (Desbarats et al. 2002).
However, due to unsupervised nature of clustering algorithms, optimality of kernel parameters does not appear so easily; with the manifold assumption of data, the spectral algorithms could therefore be applied in order for the non-linear pattern clustering.
However, the assumption of data being missing at random is inherently untestable.
Non-parametric tests were used when the assumption of data normality or homoscedasticity was not met.
To ensure robustness, we used the KW rank procedure, which does not require assumptions of data distribution.
Methods that depend on arithmetic means and standard deviations (with their assumptions of data normality) to define alerts may require data transformation.
As always with trial design, the key assumptions of data structure and relevant parameters critically affect the required sample size, and some kind of informal sensitivity analysis should always done.
In this regard, it is possible to record and store relatively long wave data sequences, whereas the commonly adopted in-practice assumption of stationary data is abandoned.
