Calculate the log prior — log

log_prior Right now this is set up to calculate the log prior for a set of parameters based on the normal distribtuion. TODO there should probably be some better way to set up and define the hyperparameters.

log_prior(params, ptable = MENDplus::MEND2013_params)

Arguments

params

params	a vector of parameters, the vector must include parameter names.
ptable	a MEND parameter table that will be updated with the values from params. MEND2013_params is used as the default paraemter table. However ptable may be set to any data frame that contains the following columns. parameter String character of the default `MEND2013_params` description String character describing the parameter. units String character of the parameter units. value Numeric values taken from the table 2 of the Wang et al. 2013

a vector of parameters, the vector must include parameter names.

ptable

a MEND parameter table that will be updated with the values from params. MEND2013_params is used as the default paraemter table. However ptable may be set to any data frame that contains the following columns.

parameter: String character of the default MEND2013_params
description: String character describing the parameter.
units: String character of the parameter units.
value: Numeric values taken from the table 2 of the Wang et al. 2013

Value

the log prior for the sampled parameters.
