A MASTER'S THESIS AT THE UNIVERSITY OF BASRAH DISCUSSES THE ESTIMATION OF THE SURVIVAL FUNCTION USING THE NEW MIXED DISTRIBUTION (POWER FUNCTION -TRUNCATED BURR |||) WITH THE APPLICATION:
On Sunday 11/12/2022 the College of Administration and Economics at the University of Basrah discussed a master's thesis in the Statistics Department on (estimating the survival function using the new mixed distribution
(Power Function -Truncated Burr |||) With the application.
The researcher's thesis (Ghufran Khaled Abdel-Hussein) aims to propose a new mixed probability distribution and derive its statistical properties in addition to estimating the distribution parameters and estimators OLS , least squarMLE and finding a survival function using the method of greatest possibility and partial estimators PS, and applying the results obtained in the study of survival data from the date of entry To the hospital until death for a sample of patients infected with Covid-19 virus.
The thesis concluded that the method of fractional estimators is preferable at large sample sizes, and that the survival function is decreasing with time, in addition to the preference of the new mixed distribution in representing real data.
