    Walkboutr: Extracting ‘Walk Bouts’ from GPS and Accelerometry Data for Physical Activity Research

    Walking is a common form of exercise and a popular intervention of interest for population health researchers. GPS devices and accelerometers, which can be worn by study participants to provide accurate information on walking duration, speed, and intensity, are an efficient and cost-effective method for measuring walking characteristics. The outcome of research on walking can inform policy...

    Increasing the Lifespan of Software for Demographic Analysis

    Many researchers face challenges with computational reproducibility. For instance, running analysis code written just a year earlier can be problematic. Even if it worked flawlessly and gave the expected results earlier, it might fail due to errors now. These issues are typically due to the use of newer versions of analysis software…

    Unlocking Population Estimation Using Readily Available Data

    Population estimation techniques rely on past population data, number of births, deaths, and migration. While various techniques have been used to accurately produce population estimates, the gold standard has been the cohort-component method. However, this method is limited by the fact that some populations may lack the appropriate indicators…
