Result: NOTE checkRd: (-1) irboost.Rd:62: Lost braces; missing escapes or markup? 62 | \item \code{weight_update_log} a matrix of \code{nobs} row by {iter} column of observation weights in each iteration of the IRCO algorithm | ^ checkRd: (-1) irboost.Rd:64: Lost braces 64 | \item\code{loss_log}{sum of loss value of the composite function \code{cfun(dfun)} in each IRCO iteration. Note, \code{cfun} requires \code{dfun} non-negative in some cases. Thus some \code{dfun} needs attentions. For instance, with \code{dfun="reg:gamma"}, the loss value is defined gamma-nloglik - (1+log(min(y))). The second term is introduced such that the loss value is non-negative. In fact, gamma-nloglik=y/ypre + log(ypre) in the \code{xgboost}, where ypre is the mean prediction value, can be negative. It can be derived that for fixed \code{y}, the minimum value of gamma-nloglik is achived at ypre=y, or 1+log(y). Thus, among all \code{y} values, the minimum of gamma-nloglik is 1+log(min(y)).} | ^ checkRd: (-1) irboost_aft.Rd:46: Lost braces; missing escapes or markup? 46 | \item \code{weight_update_log} a matrix of \code{nobs} row by {iter} column of observation weights in each iteration of the IRCO algorithm | ^ Flavor: r-patched-linux-x86_64
