I am conducting a MARK-based analysis of inland tailed frog populations in burned and unburned forests in Western Montana. I collected data over the summer and am now in the process of coding my data to use in MARK. I am using a general Robust design, with three capture groups and 3 capture occasions within each group.
During the course of field work, I was not able to collecte data on two capture occasions. I was wondering how this should be coded in MARK. Should a space ( ), period (.) or other symbol be used for missing data?
Thank you.
