Hi @yjacoby, all the attributes with an underscore are internal forest data structures not meant to be accessed by the user (_pv_values are stored prediction values), you can see available functions here
Thank you so much for your quick response @erikcs.
In regards to my second question, while predictions from a causal forest give us the treatment effect for each individual with variance estimates. I was wondering if there is a way to gain standard errors and variance estimates on the coefficients of interactions? For example if there are two covariates the coefficient, x_1* x_2 * Treatment? Of course in my case there are more than two covariates so the process of discovering the important interactions is a little more involved.
Hi,
I am new to using the grf package and am trying to understand the causal forest algorithm.
Looking at the causal forest object, what are the "_pv_values"?
A second question is, other than variable importance, can the causal forest also highlight the most 'important' variable interactions?
Thank you in advance
