The purpose behind exploratory data analysis
Webb19 jan. 2024 · Exploratory data analysis was promoted by John Tukey to encourage statisticians to explore data, and possibly formulate hypotheses that might cause new data collection and experiments. EDA focuses more narrowly on checking assumptions required for model fitting and hypothesis testing. Webb30 aug. 2024 · Cross-validation (CV) complicates this a little. The core principle is that the validation set should help you validate any decisions you make. Making decisions based on the validation set will inflate (or deflate, as appropriate) any model scores on the validation set. These inflated scores will be more representative of the training set ...
