News for Package ivtools

Changes in version 2.3.0 (2019-06-11)

Visible changes

• Correction of the help page for ivglm: h_i(\psi)=\textrm{expit}\{\hat{E}(Y|L_i,Z_i,X_i)-m^T(L_i)\psi X_i\} replaced by h_i(\psi)=\textrm{expit}[\textrm{logit}\{\hat{E}(Y|L_i,Z_i,X_i)\}-m^T(L_i)\psi X_i].

Non-visible changes

• Less internal calls to coxph.detail in stdCoxph, which makes the function slightly faster.

• Replaced class(fit)=="name" with inherits(x=fit, what="name") in places, which should be safer.

• Minor changes in the internal handling of formula arguments, to avoid errors if formulas are given implicitly to models, e.g. f <- y~x, fit <- glm(formula=f)
