Re: st: RE: coefficients constraint in nlsur and nl does not work

[渡邉真理子 <mariko.wt@gmail.com>]

Dear Brian,

Thank you .

What I typed are as follows:

nlsur( transactionvolume_s  =(cashstock2001)*({bg:
$sita_pc}+{mc})/({mc}-{ef: $s_pc2}+{bg:})) (postpayment_s = {ef:
$s_pc2}/({bg: }+{mc}))

I did also exted all variables without using global command.

nlsur( transactionvolume_s  =(cashstock2001)*({bg:
inputshareofsupplier potentialsupplier
ln_startyear_s}+{mc})/({mc}-{ef:  repaid_p_sim delayed_p_sim
default_p_sim}+{bg: })) (postpayment_s = {ef:}/({bg:}+{mc}))

But, both get the same ansuwer: two few variable specified.
