Given first and last times, observations may be dropped by one line . drop if time < firstnonmissing | time > lastnonmissing You might also want todropbothfirstnonmissingandlastnonmissingif they serve no further purpose. A tacit assumption here is thattimetakes distinct values within each pan...

Ø For the ESS, df = k-1 where k = number of regression coefficients (df = 2 1)Ø For the RSS, df = n k where n = number of observations (= 11 - 2)Ø For the TSS, df = n-1 ( = 11 1)l MS:变差除以自由度:The last column (MS) reports the ESS, RSS and TSS ...
. drop if dup>1 To drop all duplicate observations, including the first occurrence, type . drop if dup>0 Case 3: Identifying duplicates based on all the variables Obviously, one solution would be to treat this as case 1, and simply type the names of all the variables in your dataset. ...
