* Nothing: the bounds are transferred to the upper level in a (p x 1) vector by the argument resume
DESCRIPTION
Sets the bounds for a regression. The bounds remain valid until the user leaves the environment (a working space or a function). This choice can be discussed: it is not without danger, since bounds used by a program can be different from the ones the user intended to use; it mimics the Portable Troll choice and is very convenient.
EXAMPLE
bounds('1964q3','1989q2')//example taken from demo hendryericsson: bounds range from the first quarter of 1963 to the third quarter of 1989.bounds('1990f52p1','1999f52d26')// bounds range from the first week ('f52' indicates that the frequency is set to 52) of 1990 until the 26th week of 1999.bounds('1901a','1913a','1919a','1939a','1946a','2000a')// bounds cover all the 20th century years, the period of the first (years 1914 to 1918) and second (years 1940 to 1945) world wars being excluded.
