This function reports correct percentage, TP, FP, MSE and MAD from a (list of) fitted qpgee model comparing to the true betas.
compile_result(qpgee_results, beta0, cutoff = 0.1)
a vector contains correct percentage, TP, FP, MSE and MAD and its standard error if Monte Carlo simulations.
A (list of) fitted qpgee model.
True beta used in true data generation process.
Integer, the threshold to determine whether a esimated beta should be consider as 0.
