Inteff interactions not allowed
Nettet4. jun. 2014 · While running a revised xtlogit model in Stata 11 just to get familiar with the inteff command, I received this error message: "factor variables and time-series … NettetThe command inteff computes the correct marginal effect of a change in two interacted variables for a logit or probit model, as well as the correct standard errors. The inteff command graphs the interaction effect and saves the results to allow further investigation. Keywords: st0063, inteff, interaction terms, logit, probit, nonlinear models

Nettet4. nov. 2015 · Stata reports factor variables and time-series operators not allowed. I am using a large vector of controls, extensively applying the methods Stata offers for interactions. For example: state##c.wind_speed##L.c.relative_humidity. cluster2 and also other Stata packages do not allow to include such expressions as independent variables. Nettet[2009]. But I will not deal with that potential problem here.) These authors point out a common mistake, interpreting the first derivative of the multiplicative term between two explanatory variables as the interaction effect. The problem with this is that we want the interaction effect between two variables (x1 and x2) to represent how much

You can put a # between two variables to create an interaction–indicators for each combination of the categories of the variables. You can put ## instead to specify a full factorial of the ...
