Using Empirical Recurrence Rates Ratio for Time Series Data Similarity
IEEE Access, 2018 Several methods exist in classification literature to quantify the similarity between two time series data sets. Applications of these methods range from the traditional Euclidean-type metric to the more advanced Dynamic Time Warping metric.

Optimal ratio for data splitting
Statistical Analysis and Data Mining: The ASA Data Science Journal, 2022 AbstractIt is common to split a dataset into training and testing sets before fitting a statistical or machine learning model. However, there is no clear guidance on how much data should be used for training and testing. In this article, we show that the optimal training/testing splitting ratio is , where is the number of parameters in a linear ...

Average Cost-Effectiveness Ratio with Censored Data [PDF]
Journal of Biopharmaceutical Statistics, 2012 In cost-effectiveness analysis, interest could lie foremost in the incremental cost-effectiveness ratio (ICER), which is the ratio of the incremental cost to the incremental benefit of two competing interventions. The average cost-effectiveness ratio (ACER) is the ratio of the cost to benefit of an intervention without reference to a comparator. A vast

Ratio-based data envelopment analysis: An interactive approach to identify benchmark
Results in Control and Optimization, 2022 In the real world we are confronted with many cases where the ratio of input/output data is so important for managers, so in this regard we cannot use traditional Data Envelopment Analysis (DEA) models to evaluate the efficiency of decision-making units (
