Modified outlier diagnostics for the extended exponential regression model with interval and right-censored data

Abstract.: This research will explore the modified outlier diagnostics for the exponentiated exponential regression (EER) model with interval and right-censored data using adjusted residuals and some influence diagnostic measures. The EER model accommodates a monotonically increasing and decreasing...
