fit_ricker
(Package: metafolio) :
Fit Ricker linear regression
Fit a Ricker curve to spawner-recruit data and return the intercept (a) and slope (b). The model is fit via the RcppArmadillo package for speed..

run_cons_plans
(Package: metafolio) :
Run conservation plans and return the portfolio mean and variance values
This function takes a set of weights representing different conservation plans and gets the mean and variance in portfolio space. This function allows a maximally complicated set of weights to accommodate all possible scenarios. It can accommodate different spatial strategies of conservation, conserving different numbers of populations, and a lack of knowledge. You can do this by how you set your w weight object. See the example.

plot_cons_plans
(Package: metafolio) :
Plot conservation plans in mean-variance space
This makes a mean-variance plot of the portfolio output. It can take care of: plotting the individual portfolios, adding 2D kernel density polygons at two quantile levels, and adding an efficient frontier.

plot_correlation_between_returns
(Package: metafolio) :
Plot correlation of returns (i.e. metapopulation abundance) across stocks.
Create a matrix plot showing the correlation between the log returns of each stock/asset.

meta_sim
(Package: metafolio) :
Run a single metapopulation simulation.
This is the master function for running metafolio simulations. It runs a single iteration of a simulation. The arguments can be manipulated with other functions in the package to use this function as part of a portfolio analysis.
