-===== Testing different levels of sigma for catch --- no variables locked =====+====== Testing different levels of sigma for catch --- no variables locked =====
 + 
 +In this section we perform an experiment similar to [[admb_real:n3_re_catch:misfit:misfit_testing|the testing of misfit as a function of catch standard deviation]]. The main difference is that in this experiment all variables are free. We will use the same data set, namely [[admb_real:n3_re_catch:locking_variables:locking_tests#data_set_used|this one.]] 
 + 
 +===== Summary ===== 
 + 
 +As the catch sigma, sc, grows, the following trend is fairly evident: 
 + 
 +  * M grows, ultimately reaching its upper bound of 0.5 for sc = 0.2. 
 +  * q becomes smaller 
 +  * N0 becomes larger 
 +  * The discrepancy between these estimates and the VPA estimates becomes larger 
 +
