使用ensr软件包时警告很重要吗?

I am using the package ensr for estimating the coefficients of a multinomial model. The code that I use is the following:

Net_elastic_m2 <- ensr(y = DV_HAR_model2, x =IV_HAR_model2 , family = "multinomial", type.multinomial = "grouped",  maxit=10^6) 

结果准备好后,我将显示以下警告:

There were 19 warnings (use warnings() to see them)

Using the command warnings() I have the following 19 warning messages 1: In log(bigY) : NaNs produced I am not sure if the results are robust in spite of the warnings.

我认为该函数找不到最佳结果,也许我必须增加或不增加迭代次数。有人可以尝试向我解释此警告吗?
