Plot the evolution of the C matrix for a mELO model

This function plots the evolution of the elements of the C matrix for a mELO model. The C matrix has a row vector for each player, and k columns. Where k determines the complexity of non-transitive interactions being modelled.

plot_c_mat(mELO_model)

Arguments

mELO_model	a mELO_rating object with type = mELO. The output of a mELO() function call.

Value

a plot.

# mELO model with k=1
rpsfw_mELO_1 <- mELO(rpsfw_df, k=1)
plot_c_mat(rpsfw_mELO_1)
    # not stable, mELO with k=1 can't accurately model the dynamics

# mELO model with k=2
rpsfw_mELO_2 <- mELO(rpsfw_df, k=2)
plot_c_mat(rpsfw_mELO_2)
    # stable, good estimates
