### placing restrictions on coefficients sum to one

Posted:

**Thu Oct 24, 2013 12:23 pm**Hi there,

I am quite new to eviews and I have been trying to estimate a model for my thesis. This model is a PHillips Curve model and I want to put restrictions on previous π_t sum to one.

For more clarification I am posting ym model here.#

π_t=1/4 ( π_(t-1)+π_(t-2)+π_(t-3)+π_(t-4) )+α(u-u*)t+ε_t

where π_t is annualized quarterly inflation rate

1/4 ( π_(t-1)+π_(t-2)+π_(t-3)+π_(t-4) is expected inflation ( expected inflation being an average og past four quarters )

I want my restriction to be that the coefficient of expected inflation to be sum to 1.

Can someone please help me how I command eviews to do this for me! Thank you
