sacf(X_centered, d1::Int, d2::Int)

Compute the spatial autocorrelation of a centered data matrix at lag (d1, d2). Negative lags are allowed. Returns the autocorrelation as a Float64, or 1.0 if all entries of X_centered are equal.

• X_centered: the centered (de-meaned) data matrix.
• d1::Int: row lag.
• d2::Int: column lag. Use stat_sacf to compute the statistic directly from uncentered data.
