How do the default and minimum times change after joining a group

在JMP自定义设计中,当添加一个大小为k的组时,默认次数和最小次数是如何变化的,其背后的逻辑是什么?

Re: How do the default and minimum times change after joining a group

Hi @LawleyEffect608,

 

Welcome in the Community !

 

I'm not sure to have understand your question, maybe the translation is missing some parts.

What is the impact you would like to measure ? Addition of new factors in a Custom design ?

 

If you want to measure the time difference between several conditions/additions, you can use the function 

HP Time();

at the beginning and end of your design generation script, and calculate and show the time difference between the two recorded time. Make sure to fix the random seed if you really want to assess the time change only caused by your change of conditions.

 

Here is an example to record the time of a Space-Filling design generation (from How to record DoE generation time ?) :

t1 = HP Time();

DOE(
	Space Filling Design,
	{Add Response( Maximize, "Y", ., ., . ),
	Add Factor( Continuous, -1, 1, "X1", 0 ),
	Add Factor( Continuous, -1, 1, "X2", 0 ),
	Add Factor( Continuous, -1, 1, "X3", 0 ),
	Set Random Seed( 138892707 ),
	Space Filling Design Type( Sphere Packing, 60 ), Simulate Responses( 0 ),
	Set Run Order( Randomize ), Make Table}
);

t2 = HP Time();

Show( t2 - t1 );

The duration time will be visible and accessible in the Log.

Hope this answer will help you,

感谢您的回复,我想做的是定制设计中加入区组后,默认实验次数、最小实验次数是如何确定的,目前该逻辑我已研究明白,再次感谢您的回复。
