Exponential smoothing models, trend analysis, and backtesting
R is the gold standard for statistical computing and time-series forecasting. With packages like forecast , tseries , and fGARCH , R can replicate and exceed every feature found in NumXL. You can even connect R directly to Excel using packages like openxlsx or tidyxl . 2. Python (with Pandas, Statsmodels, and ARCH)
