Profile t / profile pair skecthes of Non-Linear parmests of Batesand Watts

Discussion in 'SAS (Statistical Analysis Software)' started by Winston Henry Groenewald, Dec 3, 2004.

  1. Dear SAS-Lers,

    I posted this before but did not get a response then. I am fitting a
    non-linear model and want to graphically assess the the properties of
    the parameter estimates. I particular, I want to display (and
    determine) graphically the non-linearity of the estimates using the
    profile t and profile pair skecthes due to Bates and Watts (Non-linear
    Regression and its Analysis, 1988, p205-p209).

    Has anyone developed such code before, and if you have, is it possible
    for you to share it with me?

    Thank you in advance,
    Winston Groenewald
    Pietermaritzburg, South Africa.
