Abstract: The Internet of Medical Things (IoMT) combines IoT and health sensing technologies, which allow for the early detection of various health issues. However, the data generated from IoMT devices may contain missing values or corrupted data, particularly when the missing data is of the missing not-at-random (MNAR) type. Existing solutions for imputing missing data in IoMT have limitations such as low accuracy and high computational cost. To overcome these limitations, this paper proposes an ensemble regression model (ERM) based on MNAR-type missing data progressive imputation (MDPI). The ERM-MDPI model combines three regression models, namely multilayer perceptron (MLP), support vector regression (SVR), and linear regression (LR), to improve the accuracy of imputed missing data in the cStick dataset. The experimental results demonstrate that the ERM-MDPI model-based cStick imputed dataset generated higher accuracy (93.6301%), precision (91.0385%), recall (87.0898%) and F-measure (89.0204%) than cStick missing dataset. Therefore, the proposed solution offers an efficient and accurate approach to impute MNAR-type missing data in IoMT, providing valuable insights for medical decision-making.
