Web1. Usually, the first letters in abbreviations use: M for mean (arithmetic), Md for median, GM for geometric mean. Mathematical definitions of performance metrics are shown in Appendix 2. These metrics are implemented in R Studio (e.g. packages MLmetrics, forecast) and in Azure Machine Learning Studio (e.g. Botchkarev, 2024b). WebUsing a geographic coordinate system (GCS) with values in latitude and longitude may result in undesired distortion or cause calculation errors. Errors are calculated for one of the three transformation methods: affine, similarity, and projective. Each method requires a minimum number of transformation links.
