I'm using this code to calculate age in months using two different methods: x_age_mn_m1 = intck("month", dob, 1_date)+0.5; x_age_mn_d1 = intck ("day", dob, 1_date)/30.43; x_age_mn_m2 = intck("month", dob, 2_date)+0.5; x_age_mn_d2 = intck ("day", dob, 2_date)/30.43; The code works fine, but there are improbable values generated for the age_mn variables (x_age_mn_m1 and x_age_mn_d1) one of the inputs, only one! Why does this happen, and how can I solve it? Thanks! ID DOB 1_date x_age_mn_m1 x_age_mn_d1 2_date x_age_mn_m2 x_age_mn_d2 z 05/23/2012 03/30/3017 12058.5 12060.93 05/15/2017 60.5 59.744
