Superiority of an ANN model was demonstrated by site-averaged (monthly) relative error of 5.85% compared with 10.23% (MLR) and 9.60 (ARIMA) with Willmott's Index of 0.954 (ANN), 0.899 (MLR) and 0.848 (ARIMA).

After removing the IRI model-simulated GPS RO (radio occultation) retrieval errors from the original F3/C measurements, the average values of the annual and monthly mean percentage errors of the F3/C-measured RO retrieval errors of the E region electron density can be substantially reduced (Wu et al. 2015).

Data transfer from weekly to monthly forms demonstrated errors on the monthly reports and minimal supervision was provided to address the issue.
We have used monthly mean sampling error-corrected geopotential height fields on isobaric surfaces (about 190 levels covering 800 hPa to 3 hPa) from radio occultation (RO) measurements and computed geostrophic and gradient wind fields at ∼500 km horizontal resolution outside the tropics over 2007 to 2012.
The idea is simple in theory: by collapsing six existing benefits into one monthly payment, fraud and error will be minimised and running costs reduced.
Although the use of the monthly ratio introduces some error in that variable, much of the variation in species mass is across cities, and between months within cities.
Nonetheless, when considering the standard error around monthly estimates of home-range size and DDD, Reitz and Léonard [ 33] showed that variance was high during this time, suggesting strong heterogeneity amongst individuals.
