i have 0 values replicate , sampling weights. therefore, when use svycoxph “survey” package, error message “package invalid weights, must >0”. think 1 way might exclude these observations. wonder if there way keep observations cox proportional hazards model? thanks! julia zero replicate weights normal -- jackknife replicates observations psu being left out; bootstrap replicates psus appeared 0 times in particular resample. 0 sampling weights, on other hand, don't make lot of sense , indicate observations aren't in sample or aren't in sampling frame (personally, i'd code these na ) the coxph() function in survival package can't handle negative or 0 weights, , that's svycoxph() calls. replicate weights, svycoxph() adds small value (1e-10) weights stop problems zeros. however, svycoxph() can't handle 0 sampling weights. want remove these before constructing design object.

for problem, first take in 2 strings using fgets. need check if string comprised entirely of digits making number. able part recursively, next task if strings numbers, need sum them recursively well. example, output of program may this: first number > 9023905350290349 second number > 90283056923840923840239480239480234 sum 90283056923840923849263385589770583 again, need recursively, thinking march along stream of digits , add them together, not sure how write program recursively. since input in character form, have convert integer, believe can converting individual characters integer ascii value subtracting 48 away it. appreciated. thanks! you're on right track. recursive approach checking if input number looks following, right? notice can go ahead , subtract '0' character without bothering convert 48 yourself. int number_length(char *s, int pos) { int d; if (s[pos] == '\0') { return pos; } d = s[pos] - '0'; if (...
