The article introduces a new method to test if economic data trends over time while considering fluctuations in variance. Traditional tests are not reliable in such cases. The new weighted forward-detrending scheme helps to accurately analyze trending data with varying variances. The researchers found evidence supporting the idea that health care expenditures as a share of GDP in OECD countries are not stable over time.
