Piezoelectric Energy Harvesting
The coefficient of determination, denoted as $$R^2$$, is a statistical measure that indicates the proportion of variance in a dependent variable that can be predicted from an independent variable. It provides insight into how well the data fits a statistical model, with values ranging from 0 to 1, where 0 indicates no explanatory power and 1 indicates perfect prediction. In the context of circuit parameter extraction and experimental validation, this metric is crucial for assessing the accuracy and reliability of models used to describe piezoelectric energy harvesting systems.
