A list generated from Surv_Simul() containing the following elements: a simulated survival dataset (surv_simul_db), the dataset describing the survival characteristics of the population (surv_pop_db) and a plot illustrating both (surv_plots). The specified simulation parameters (arguments) in Surv_Simul() are fish_num_per_tank = 100, tank_num_per_trt = 4, treatments_hr = c(1, 0.7, 0.5), logHR_sd_intertank = 0, n_sim = 10, plot_out = TRUE.
