Why Smart Models Lost to a Simple Guess

A basic rule of just repeating last year’s numbers beats complex machine learning models when analyzing this public health dataset. This project pulls six years of vaccine records for thirteen districts, then acts like a detective to find hidden errors. It discovered that most data points were exact copies of the previous year, meaning the information wasn’t real. It also found that entire months had been swapped in order. Because the data was so repetitive, a simple forecast outperformed advanced statistical tools. The real lesson here is that checking your data for weird patterns matters more than choosing the fanciest algorithm.
