[Basta-users] Are b1 and d1 dates priors?

[Colchero, Fernando]

Hi Cliff,

   Unfortunately at this point BaSTA only takes known dates (in years), but we are planning to allow the users in the future to have proximate values, like upper and lower possible values for ages. In the current version, the best will be to replace with 0 those records for which there is uncertainty with the dates. 

  Best,

  Fernando

	Dear BaSTA,

	In the data frame we are allowed to specify birth and death dates.  Are these taken as certain values, or as priors?  For example, if I have an approximate idea of birth, but only approximate, should I include it?
	
	
	
	All the best!
