setSelection sets the banker parameters of a parameterDef object. setSelection are "call by reference", so assignment is not needed to update the parameterDef object. In other words, they will overwrite the value of its argument(parameterDef object). parameterDef is a short hand of "parameter definition". It defines parameters used by the dgp which is the most important part of a simulation. For each simulation,There is a particular set of parameter. parameterDef allow us to define several parameters for different simulation at once. There are two types of parameter in parameterDef, scalar parameters and other parameters. Scalar parameters must be a scalar. Any vectors or matrix is regarded as a sequence of scalar parameters. For example, n=seq(10,50,10), first simulation takes n=10, second simulation takes n=20 and so on. Other parameters can be anything and it is banker over the scalar parameters. For example, we would like to know how would the sample size affect the variance of the sample mean of normally distributed variable. We can set n=seq(10,50,10), mean=1 and sd=2. (see example)#'
Merge two ezsim objects. Either m or parameter_def of two ezsim objects must be the same. If parameter_def are the same, the merging is regarded as increasing the number of simulation m. If the parameter_def are different and m are the same, the merging is regarded as extending the parameter_def. Notice that, use_seed will not be merged!
A quick summary to the simulation. Summary statistics included mean, true value (tv), bias, bias percentage (mean/tv-1), sd, rmse (root mean square error), min, q25 (first quarter), median, q75 (third quarter), max, p value of jb-test. See ezsim and plot.summary.ezsim for details and examples.
