Dear all,
I tried help.search("karber") and RSiteSearch("karber") and
RSiteSearch("*karber*") to find whether the (trimmed) Spearman-Karber method
for LD50 evaluation in toxicity data (e.g. according to Hamilton 1977) has been
implemented in R. Or does this method feature under a different name? Of course
logit and probit are doable, but Spearman-Karber seems to me to be the way I
should go with our data.
Thanks for all your help,
Susanne
