Error : G0159 Wrong number of parameters

Hello,
I have looked over your code and have a few suggestions. I was unable to run your code because I do not have your data. However, I have noted a couple of things. First in defining your independent variables, veq1 and veq2, you use the variable const. However, it appears that you have not defined const prior to using it to define your independent variables.

The second issue, and more likely reason for your error code, is that you have four inputs into the lsur procedure. The lsur procedure requires 5 inputs. The proper usage is:

Q = LSUR(dataset,LHS_vars,RHS_vars,NUM_var,Restrict);

You are currently missing the Restrict input. The source code (or user manual) provides the following description of Restrict:

** Restrict -- String, constrained information on parameters

** to perform restricted estimation. The syntax

** of Restrict is as follows:

**

** Restrict="rest1, rest2,...., restN";

**

** More than one restriction is allowed provided

** each is separated by commas. Each restriction

** must be written as a linear equation with all

** variables in the left-hand side and the constant

** in the right-hand side (i.e., x1:1+x1:2=1).

** Variables shown in each restriction must be

** variables in the regression model. Note that

** the numeric value following the (:) signifies

** which equation the variable comes from (i.e.,

** X4:10 indicates the X4 variable comes from the

** 10th equation). Restrictions in the RESTRICT

** argument must be consistent and not redundant

** otherwise error messages will be given. Users

** should note that only the parameters associated

** with the variables are restricted, and not the

** variables in the model.

**

** Examples of some restrict arguments:

**

** 1) Restrict="x1:1 + x1:2 + x1:3 = 1";

** 2) Restrict="const:1 + const:2 + const:3 = 1,

** trend:1 = 0,

** trend:2 = 0,

** trend:3 = 0";
