constrains / boundaries
Posted: Thu Jul 12, 2018 8:15 pm
I am running a model with different scenarios to forecast vacancy rates in a commercial real estate market. Please see the screenshot attached with the model equations.
I want to restrict the occupied space series (occupspc_sp) to not surpass 95% of the total stock series (stock_sp), so that the vacancy rate (vacan_sp) never goes below 5%. The idea is that if the occupspc_sp series surpass 95% of the stock_sp series EViews would keep the occupspc_sp at the maximum level of 95% of stock_sp. Occupspc_sp is calculated in Eq3 as an inline text equation (identity). Stock_sp is calculated in Eq11 and is also an inline text equation.
How can I accomplish this ?
Thanks
