Log transformation is commonly used to normalize extremely skewed data in data analysis.The article discusses a project analyzing energy consumption of training AI models.The dilemma of whether to use log-transformed response variables or log link functions is explored.Comparison of models using AIC values and diagnostic plots is detailed, favoring log-transformed models.The article interprets coefficients in models and discusses the impact of log transformations on interpretation.Results show log-linked models provide more sensible outcomes compared to log-transformed models.The importance of understanding the difference between log transformation and log link in modeling is emphasized.Log transformation may distort variation and noise in the data, affecting model reliability.Detailed comparisons, plots, and interpretations are presented to illustrate the impact of transformation decisions.Utilizing log-linked models can provide more accurate and meaningful results in data analysis.
