Title: Bayesian Inference of Binary, Count and Continuous Data in Toxicology
Version: 0.1.2
Description: Advanced methods for a valuable quantitative environmental risk assessment using Bayesian inference of several type of toxicological data. 'binary' (e.g., survival, mobility), 'count' (e.g., reproduction) and 'continuous' (e.g., growth as length, weight). Estimation procedures can be used without a deep knowledge of their underlying probabilistic model or inference methods. Rather, they were designed to behave as well as possible without requiring a user to provide values for some obscure parameters. That said, models can also be used as a first step to tailor new models for more specific situations.

Further arguments to be passed to generic methods

Value

Plotting method for FitTT objects.

Description

This is the generic plot S3 method for the FitTT class. It plots concentration-response fit under target time analysis.

The fitted curve represents the response at the target time as a function of the concentration of chemical compound; When adddata = TRUE the black dots depict the observation data at each tested concentration. Note that since our model does not take inter-replicate variability into consideration, replicates are systematically pooled in this plot.

The function plots both 95\ (by default the grey area around the fitted curve) and 95\ intervals (as black segments if adddata = TRUE), either binomial, poisson or normal for respectivelly, BinaryFitTT, CountFitTT andContinuousFitTT. Both types of intervals are taken at the same level. Typically a good fit is expected to display a large overlap between the two intervals.

If spaghetti = TRUE, the credible intervals are represented by two dotted lines limiting the credible band, and a spaghetti plot is added to this band. This spaghetti plot consists of the representation of simulated curves using parameter values sampled in the posterior distribution (10\ taken for this sample).

Usage

  x,
  xlab = "Concentration",

This is the generic plot S3 method for the PPC class. It plots the predicted values with 95 \ values for FitTT objects.

The bisecting line (y = x) is added to the plot in order to see if each prediction interval contains each observed value. As replicates are shifted on the x-axis, this line is represented by steps.
