Auditing and Exploring Dielectric Measurements of Water R package DielectricWaterR version 0.2.0 Imports, audits, compares and visualises dielectric measurements of water under fuel contamination and ageing. Provides descriptive summaries, frequency-response comparisons, confidence intervals based on physical-unit means, and training and testing splits that keep observations from the same experimental unit together. Experimental-unit safeguards address pseudoreplication concerns discussed by Hurlbert (1984) <doi:10.2307/1942661>. Grouped splitting is consistent with the structured-data validation principles discussed by Roberts et al. (2017) <doi:10.1111/ecog.02881>. Student t confidence intervals use the standard mean-interval formula described in the NIST/SEMATECH e-Handbook of Statistical Methods <https://www.itl.nist.gov/div898/handbook/eda/section3/eda352.htm>. Experimental-unit identifiers are supplied by the user and are not inferred from material labels. This research prototype does not provide validated contaminant prediction or causal inference.
