Dear Statalisters
I need to set up an if loop but am having trouble with the syntax. I want
to calculate the upper and lower 95% confidence intervals for the
standardised incidence rate of a specific cancer over several years. There
are two ways of calculating these upper and lower bounds depending on how
many registered cases there were of that particular cancer with the
benchmark set at 500. I have the total number of registrations per year
setup as a variable (total) in the datasheet as follows
year total
1985 353
1986 427
1987 359
1988 363
1989 356
1990 364
1991 326
1992 318
1993 338
1994 323
1995 329
1996 318
1997 313
1998 318
1999 317
2000 309
I also have a matrix (reg) setup which contains one column containg the same
number as the variable total
reg[16,1]
total
r1 353
r2 427
r3 359
r4 363
r5 356
r6 364
r7 326
r8 318
r9 338
r10 323
r11 329
r12 318
r13 313
r14 318
r15 317
r16 309
What I need to know is how to open the if loop i.e.
if .....<500 {
Thank you very much for your time,
Christopher D Fergusson
