I got many errors: ERROR: (execution) Invalid operand to operation and ERROR: (execution) Matrix has not been set to a value

[etty]

Hello everyone,

I am trying to calculating Elasticities in almost ideal demand system (I follow the tutorial at Calculating Elasticities in an Almost Ideal Demand System) And I use my own resarch data as an input. But I got many errors:

ERROR: (execution) Invalid operand to operation

ERROR: (execution) Matrix has not been set to a value

Any help would greatly appreciated. I attached the log file, please have a look.

Thankyou

Regards,

fix the first error, the missing bracket and then try it from there.

568      estimate 'elasticity cl' ((gclcl - bcl*(.138))/.138 -1;
