gdp = rnorm(50, 100, 10),
ntl = rnorm(50, 50, 5) #ntl is nightime light index from Google Earth Engine (GEE)
)
senser(df, proxy = "ntl", target = "gdp") #English explanation by defaultThe composite score integrates: (1) Spearman monotonicity; (2) R-squared information content; (3) Elasticity responsiveness; (4) Coefficient of variation; (5) Absolute change; (6) Ceiling effect; and (7) Beta stability.
