Dear Srinivas,<br> Actually I have not worked in statistical correlation methods till now. But I know that Prof.H.S.Ram Mohan and Prof.K.MohanKumar in my Department has worked a lot in this area. Their students Mr.Rajesh.J. and Lorna.P.Nayagam has published one paper regarding these techniques in an international journal. You can contact any of the professors for the clarification of this doubts. Both of them are friendly to me.<br>

I have two different files with the same dimension (x,y,t).<br>I wish to compute the Standard
Deviation (SD) and correlation coefficient.<br>Lat time I asked the same question in the GrADS User List<br>They suggested me to use 'set gxout stat' command.<br>If I use the command it gives only one value of SD (it founds from all the available <br>
grid points (spatial) at one time.<br>But I need to find the temporal correlation (temporal values have to be<br>used for the computation of SD) and so finally we will get<br>a spatial map of SD and Correlation coefficient.<br>
Please suggest me to get this.<br>If any Mathematical functions are available in GrADS please let me know.<br>Otherwise any GrADS script file will help me to find them.<br>Thanking you<br>D Srinivas</font></font><div> </div>
