[Limdep Nlogit List] WTP

[Mahsa Taslimi]

Hi

 I got a problem with Estimating WTP in the LCRPL model. it is
overestimated. I have 3 levels for the price: 400 (status quo), 1000 and
2000. The MWTP is above 2000.

LCRPLogit ;lhs=choice ;choices=type1,type2,type3
;model:
u(type*)= a1*fn+a2*mhz+a3*egh+a4*si+a5*ej+a6*pr
;rpl ;halton
;draws=500
;fcn=a5(n) ;pds=8
;lcm ;pts=2
;Par ;wtp =  a1/a6, a2/a6, a3/a6, a4/a6, a5/a6
;Parameters
;Effects : fn(*)/pr(*), mhz(*)/pr(*), egh(*)/pr(*), ej(*)/pr(*),
si(*)/pr(*)   $
MATRIX ;list ;1/79 *wtp_i'1 $
MATRIX ;list ;1/79 *classp_i' 1 $

can you please help me with this?
