Web30 mei 2024 · The answer is simple. The goal is to keep the significant occurrences. so if for example you set the SL = 0.1, the P_values greater 0.1 are insignificant and the P_values smaller or equal to 0.1 are considered significant. The higher the P_value, more insignificant the predictor (occurrence) and the coefficient closer to zero (H_0).
