AdjLBA Function

Format

i = adjlba(lower_cmc1,upper_cmc1,lower_cmc2,upper_cmc2,age);

Description

The adjlba function adjusts the lower bound of the century month code (CMC) of an event based on an age. It is generally used to calculate the minimum date of birth based on the date of an interview.

The lower_cmc1 and upper_cmc1 arguments are numeric expressions generally representing the date of birth CMC range. The lower_cmc2 argument is a numeric expression of the CMC of an event, generally the date of an interview. The upper_cmc2 argument is not used (but is used by adjuba). The age argument is a numeric expression expressing the age of the person in complete years.

Return Value

The function returns the adjusted lower bound of the CMC of an event based on the age. If the adjusted lower bound is greater than upper_cmc1, the function returns the error code of -1.

Example

t = adjlba(ldob,udob,di,di,HL6);
