An age effect has been introduced in the data by dividing subjects in five age classes (0-44; 45-54; 55-64; 65-74; 75+) with corresponding hazard ratios 0.8, 0.9, 1, 1.3 and 1.8 . use strs_stnetresults,clear (simulate: survsim) . list , noobs abbrev(16) +---------------------------------------------------------------------------+ | End of C O V E R A G E B I A S | | interval EdererII PoharPerme EdererII PoharPerme | | (strs) (stnet) (strs) (stnet) | |---------------------------------------------------------------------------| | 1 .952 .952 .0004031 -.0008732 | | 2 .965 .956 .0012043 -.0007361 | | 3 .963 .963 .0024372 -.0002693 | | 4 .959 .97 .0035616 -.0000499 | | 5 .964 .966 .0042613 -.000088 | |---------------------------------------------------------------------------| | 6 .948 .963 .0050199 -.0001277 | | 7 .949 .96 .0057368 -.0005793 | | 8 .946 .958 .0067513 -.0004624 | | 9 .94 .956 .007483 -.0006708 | | 10 .93 .947 .0085158 .0001158 | |---------------------------------------------------------------------------| | 11 .924 .951 .0092528 .0002983 | | 12 .929 .947 .0096973 .0004228 | | 13 .922 .95 .0106211 .0009953 | | 14 .913 .948 .0112986 .0006611 | | 15 .911 .956 .0122146 -.0011481 | |---------------------------------------------------------------------------| | 16 .904 .954 .0130301 -.0008705 | | 17 .904 .954 .0137129 -.0017143 | | 18 .899 .953 .0143532 -.0017661 | | 19 .897 .949 .0152267 .0009595 | | 20 .888 .945 .0157067 .0024169 | +---------------------------------------------------------------------------+ . tabstat inci_strsRS_end-bias_stnet, varwidth(16) col(statistics) variable | mean -----------------+---------- inci_strsRS_end | .93035 inci_stnet_end | .9549 bias_strsRS | .0085244 bias_stnet | -.0001743 ----------------------------
