set variable to random number.

lisamaley — Fri, 09 Jun 2023 23:27:14 GMT

I want to set variables to random numbers. I tried this. but it is not working

MEnum = 5;
For( i = 1, i = MEnum, i++,
	betai = Random uniform.( 30, 50 )
);

When I print this to the log it just keeps giving me random numbers, how do I get 5 different random numbers for beta1 to beta5?

I would do it this way

beta = {};
MEnum = 5;
for (i=1,  I<=MEnum,i++,
      beta[i] = Random uniform. (30,50);
);

and change i=MEnum to i<=MEnum

I tried

beta = {};
For( i = 1, i <= MEnum, i++,
	beta[i] = Random uniform.( 30, 50 );
	Print( betai );
);

MEnum is based on how many columns are selected. I checked this out and it is working.

but I get this error:

Name Unresolved: Random uniform. in access or evaluation of 'Random uniform.' , Random uniform.( 30, 50 ) /*###*/

I tried

beta = {};
For( i = 1, i <= MEnum, i++,
	beta[i] = Random uniform.( 30, 50 );
	Print( betai );

);

MEnum is defined above all this and is working fine.

But I am getting this error:

Name Unresolved: Random uniform. in access or evaluation of 'Random uniform.' , Random uniform.( 30, 50 ) /*###*/

Nevermind, I took out your period and it works. I copied without paying attention. thank you!

Very nice lesson, @txnelson . I would also offer this way:

beta = J( MEnum, 1, Random Uniform( 30, 50 ) );
