Thirteen monotonic(sigmoidal) equations ("Hill", "Hill_two", "Hill_three", "Hill_four", "Weibull", "Weibull_three", "Weibull_four", "Logit", "Logit_three", "Logit_four", "BCW(Box-Cox-Weibull)", "BCL(Box-Cox-Logit)", "GL(Generalized Logit)") and four non-monotonic(J-shaped) equations ("Brain_Consens", "BCV", "Biphasic", "Hill_five") are provided to fit concentration-response data.

The formula of requested equations (with abbr.) will show up.
