sensSAM | R Documentation |
Estimate of the parameters of a statistical age model using a number of sigmab values.
sensSAM(EDdata, model, sigmaVEC = NULL, iflog = TRUE,
maxcomp = 8, plot = TRUE, outfile = NULL)
EDdata |
matrix(required): a two-column matrix (i.e., equivalent dose values and |
model |
character(with default): the fitting model, one of |
sigmaVEC |
vector(with default): a series of sigmab values that will be used as inputs for the model. For example, |
iflog |
logical(with default): transform equivalent dose values to log-scale or not |
maxcomp |
integer(with default): the maximum number of components in the FMM |
plot |
logical(with default): logical value indicating if the results should be plotted |
outfile |
character(optional): if specified, the results will be written to a CSV file named |
Return an invisible list that contains the following elements:
pars |
a list that contains the optimized parameters for each sigmab value |
mat |
a matrix that contains the optimized parameters, the maximum logged likelihood value, and the corresponding Bayesian Information Criterion (BIC) value |
