egttools

The egttools package implements methods to study evolutionary dynamics.

Functions

calculate_expected_group_success	Calculate the expected group success eta_G under the stationary distribution.
calculate_expected_indicator	Calculate E[f] = sum_s sd(s) * sum_g P(g|s) * f(g) for an arbitrary indicator f.
calculate_expected_indicators	Calculate E[f_k] for multiple indicator functions in a single pass.
calculate_expected_indicators_precomputed	Compute expected indicators from a precomputed indicator matrix (pure C++, GIL released).
calculate_expected_payoff	Calculate the expected payoff averaged over the stationary distribution.
calculate_expected_state_indicator	Calculate E[f] = sum_s sd(s) * f(s) for a single state-level indicator.
calculate_expected_state_indicators	Calculate E[f_k] = sum_s sd(s) * f_k(s) for multiple state-level indicators in one pass.
calculate_expected_state_indicators_precomputed	Fast path: E[f_k] = sum_s sd(s) * indicator_values(s, k) using a precomputed matrix.
