denote the input values for each row, the computation equations can be expressed as follows
Compute descriptive statistics on data rows
1. rowstats irng:=col(1)[1]:col(10)[1] mean:=mymean
2. rowstats irng:=col(1)[1]:col(5)[3] min:=Col(6) max:=Col(7)
Please refer to the page for additional option switches when accessing the x-function from script

This X Function can be used to describe the basic aspects of each row of data in a specific range, including the mean score, standard deviation, standard error of mean, minimum value, maximum value, sum and number of non-missing values.
1. To return the standard deviation of an active rows, use the script command:
rowstats sd:=mysd; mysd=
2. To open the dialog of rowstats, use the script command:
rowstats -d;
Let denote the input values for each row, the computation equations can be expressed as follows
