Error: Equation too complex or Syntax Error

[chrgordon27]

Hello,

I've just begun using a version of EVIews 8 Student for an assignment I have, and have run into trouble.

We are running very simple OLS estimations of linear equations of varying sizes, using panel data imported from excel. We have data on 11 variables, one dependent and 10 independent. I have had success with equations containing 6 parameters, but anything more than that and I get an Error message: "Equation too complex or Syntax Error".

For example:
e=c(1)+c(2)*y+c(3)*p+c(4)*r+c(5)*m+c(6)*a <--- Works fine

e=c(1)+c(2)*y+c(3)*p+c(4)*r+c(5)*m+c(6)*a+c(7)*d+c(8)*tmax+c(9)*tmin <---- returns the error

Is this due to some restriction in the Student Version, or is there something else I'm missing...

Any help kindly welcomed!
Charlie.

Try changing the variable "d" to another name and see if that helps.

You were on the right track, and indeed EViews was already up ahead of me and thinking like you were. It had changed the name of my dataset for the variable "d" to "d01", which meant my equation trying to estimate "d" was never going to work. Thank you for the pointer. The variable name "d" is obviously reserved for some other purpose then...
