The ltrend script, qdims.gsf and the example you have mentioned is working. but in your example in the 4th line 'ltrend sst sstl s e' , sst is the variable the trend of which i want to calculate, i understand but what are sstl, s, and e. here which is the regression coefficient(b) which i need to show the trend(slope). also in the last line what is 'a' in 'd a'. you have not defined it earlier. Please tell me.<br></div>Thanks<br></div>Anubhav<br><div><div><br></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Dec 1, 2014 at 11:04 PM, Carlos Batista <span dir="ltr"><<a href="mailto:krlosbatist@gmail.com" target="_blank">krlosbatist@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi Debanjana Das!!!
