Hi there,
Hope someone can help me on this one ..
I'm trying to understand how to fit dummy and continuous variables at
the same time - at the first level if one specifies some continuous
variables like motion regressors, the betas are the same whether you
enter other dummy regressors or not - by contrast the betas of the dummy
regressors do change ; can someone tell me how this last part is
computed? (what is the Y par now?)
cheers
