Further, all test statistics account for such missing returns on a daily basis. The issue will prompt for the details such as the steps to reproduce the, The GitHub page also has a wiki with a larger gallery of examples of paralleliz, package allows users to take advantage of multiprocessor machines for many. {cmdab:factor10(}{it:factor_return10}{cmd:)} {cmdab:factor11(}{it:factor_return11}{cmd:)}
At least in my experience this was critical.
In this section we discuss basic usage of the commands in some common use. {p 8 16 2}
{p 4 8 2}{cmdab:eswlb(}{it:estimation_window_lower_boundary}{cmd:)} specifies the lower boundary of the estimation window, measured in trading days relative to the event date. Results not explicitly saved in the child processes' datasets will not be. % This file should only be changed according to the AUTHOR notes below. This allows all flavors of Stata to take advantage of multiprocessor machines. It pools together combinations when there are fewer child processes than, If Stata-style semantics are needed, the solution is to add, parallel, by(byvar): by byvar: egen x_max = max(x). Computing times for each run of a basic bootstrap problem. and if child Stata processes are killed by the operating system.

Calling this option might increase the calculation of test statistics dramatically since resource requirements to calculate the Kolari and Pynnnen adjustment increase quadratically in the number of events. {p 8 16 1}

Improved methods for tests of long-run abnormal stock returns. On the other hand, overall, as the problem size (number of simulations. is executed, and the resultant data is saved.

The rest of the paper introduces more details about the usage of the command, and provides examples and benchmarks for the reader to get a better understandi, In this section we discuss the syntax of the, subcommands, technical details of execution, and results returned from, subcommands for initialization, parallel task execution, cleanup, and possibly, diagnostics (for those cases in which the user needs to debug failures, The main usage of this command is to set the number of child processes to, \begin_inset Formula $\max(\lfloor(\mathrm{num\ processors})\cdot0.75\rfloor,1)$, If there are multiple processors, the default will leave some free for, other computer interactions, which should be fine for testing on a personal, Note that when using Stata/MP with child tasks that are automatically paralleli, zed by Stata, care should be taken with this option and the, option for the execution so as not to inadvertently use more processors, - To prevent slowdowns due to context switching between tasks there is, a soft limit that restricts setting the number of child processes to be.
