ROOT MEAN SQUARE ERRORName:
<SUBSET/EXCEPT/FOR qualification> where <y> is the response variable; <par> is a parameter where the computed root mean square error is saved; and where the <SUBSET/EXCEPT/FOR qualification> is optional.
<SUBSET/EXCEPT/FOR qualification> where <y1> is the first response variable; <y2> is the second response variable; <par> is a parameter where the computed difference of root mean square errors is saved; and where the <SUBSET/EXCEPT/FOR qualification> is optional. This syntax computes the root mean square error of <y1> and <y2> and then computes the difference of the two root mean square error values.
LET A = ROOT MEAN SQUARE ERROR Y1 SUBSET TAG > 2 LET A = DIFFERENCE OF ROOT MEAN SQUARE ERROR Y1 Y2
LET Y1 = NORMAL RANDOM NUMBERS FOR I = 1 1 100 LET RMS = ROOT MEAN SQUARE ERROR Y1A value of 0.9256 is returned.
