**qpcon b <sign> [constant][*]ai [< > [constant][*] aj ...]**This command establishes constraints on parameters for a linear regression equation. <sign> is ‘<’, ‘=’, or ‘>’ (“<=” and “>=” also are accepted but are recorded as strict inequality constraints). <constant> terms are optional scalar multiples for the respective parameters. An asterisk may be included to clarify that the parameters are multiplied by the corresponding constant. The parameters are denoted by <ai>, where ‘i’ is the position in the regression equation of the corresponding variable. If a constant is included in the regression, then the parameters are denoted as a1, a2, .... Right-hand-side terms are separated by either a ‘+’ or ‘-‘.

Examples:

qpcon 25.0 > a1 # constrain the constant qpcon 13.0 = 1*a2 + 1*a3 # constrain the sum of slope parameters Related Topics: Soft Constraints, :ref:`con <G7RMcon>`
