AdjUBA Function

Format

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

Description

The adjuba function adjusts the upper bound of the century month code (CMC) of an event based on an age. It is generally used to calculate the maximum 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 not used (but is used by adjlba). The upper_cmc2 argument is a numeric expression of the CMC of an event, generally the date of an interview. The age argument is a numeric expression expressing the age of the person in complete years.

Return Value

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

Example

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