Root mean square error of approximation (RMSEA) The RMSEA (Steiger, 1980) is a widely used fit measure in structural equation modeling:
The root mean square error of the traditional TOA localization method is 1.131, the root mean square error of the TOA fingerprinting localization method without particle filtering is 0.693, and that of the TOA fingerprinting localization method based on particle filtering is 0.563.
The dimension parameters are the square root of amplitude, root mean square, mean value, and peak value, which are defined as follows [35]:
Similarly, root mean square error (RMSE) is the measure of average magnitude of the error.
