Distributed ledger: A shared database with a consensus mechanism, ensuring identical copies. Simple Linear Regression Correlation: Ny = covXY (sx )( sy ) t-test for r (n —2 df): t = r>/n —2 V l-r 2 cov xy Estimated slope coefficient: CFA® E x a m M SR = RSS / k. • M SE = SSE / (n - k - 1). • Test statistical significance o f regression: F = M SR / M SE with k and n - k — 1 df (1-tail). Risk Types: Appropriate m ethod D istribution o f risk Sequential? Accommodates Correlated Variables? • Standard error o f estimate (SEE = >/MSE ). Smaller SEE means better fit. • Coefficient of determination (R 2 = RSS / SST). % o f variability o f Y explained by Xs; higher R 2 means better fit.
