transform data into log

[coelhoindy]

hi,

I want to transform my variable into log but it gives me the following messageL

String argument passed to numeric log function

And then if I try to run a regression with the variable I get this message: syntax error.

if I include more than two variables, I get this message: alpha series in specification -net_income @ expand can convert to catagorical dummies

anyone can help?

The log function only works on numbers. You've passed in a string variable. EViews cannot take the log of strings.

how to eliminate a string variable?

Assuming your string variable contains numbers stored as a string (possible, but unlikely), you can create a series with something like:

Code: Select all

series myseries = @val(myalpha)

where myalpha is the name of your alpha/string series.
