===strip_*.m (deleted in readjusted code)===
Versions of files that only use the parameters task = 'monte_data', use_solver = 'ga', and estimator = 'MSM' (which apparently are the only solvers and estimators that work, but unverified). Removed because could not handle task = 'data'.

*GMM: Generalized Method of Moments
*MSM: Markov State ModelMethod of Simulated Moments
*MLE: Maximum Likelihood Estimation
*GA: Genetic Algorithm
*SE:Standard Error
==How to run==
'''error_type''' (currently hard coded as 1 and isn't fully written to support 2): 1 for match specific errors, with the error distribution following an exchangeable structure. var(e) = sig^2, and cov(e,e') = 1/4*sig^2. 2 for agent specific errors, with the error structure of match <i, j> as sig*ei*ej.
===gmm_2stage_estimation.m===
This is the fitness function. Takes a vector and returns a scalar. GA minimizes this function.
===moments.m===
Generates the moments needed for the GMM.
==Location/Structure of Data==
'''empirics_match_specific_2nd_stage_ga''':
'''empirics_match_specific_with_se''': Saved if task = 'data'
'''type_(error_type)_monte_mktsize_(mktsize)_K_(K)_S_(S)_rep_(montenn)''':
because it returns a scalar, but should return a 166x1 vector.
Better fix notes:
The problem is narrowed down to the section of mkt_resample.m before the call to moments. Somehow the parameters to moments are changed such that it returns a scalar.
Solution found (I think):
monte_M cannot be set to 1. For values greater than 1, the program seems to work. It doesn't crash, anyway.
==Profiling==
Monte_data and monte run much faster than data, because data is so large.
==Notes==
There is a lot of unused code. For example, monte_std and monte_x seem to only be assigned, not used.
