Hello everybody; I have one little problem with Gretl. When I try to do the periodogram of my time series, the program tells me the next: "This application requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information" My data set is: 1998:01 -0,336567 1998:02 -0,601012 1998:03 0,054091 1998:04 0,114192 1998:05 -0,030051 1998:06 -0,024040 1998:07 0,226882 1998:08 0,226882 1998:09 0,931569 1998:10 0,453019 1998:11 0,108182 1998:12 0,841417 1999:01 0,054091 1999:02 0,402678 1999:03 -0,036061 1999:04 -0,102172 1999:05 -0,246415 1999:06 -0,024040 1999:07 -0,193826 1999:08 -0,193826 1999:09 -0,751265 1999:10 -0,338827 1999:11 -0,396668 1999:12 -0,541162 2000:01 -0,080596 2000:02 -0,296419 2000:03 -0,027106 2000:04 0,078071 2000:05 0,823807 2000:06 0,489524 2000:07 0,192174 2000:08 0,192174 2000:09 0,279170 2000:10 0,223126 2000:11 0,348587 2000:12 0,481061 2001:01 0,466385 2001:02 0,243230 2001:03 0,333381 2001:04 0,011600 2001:05 -0,620305 2001:06 -0,369322 2001:07 -0,386563 2001:08 -0,467395 2001:09 -0,001022 2001:10 -0,157556 2001:11 -0,001142 2001:12 -0,578594 2002:01 0,582287 2002:02 -0,005250 2002:03 -0,159511 2002:04 0,141236 2002:05 0,923617 2002:06 0,208532 2002:07 0,664167 2002:08 0,118583 2002:09 1,120839 2002:10 0,233164 2002:11 0,439523 2002:12 0,596064 2003:01 -0,219542 2003:02 0,520915 2003:03 0,351373 2003:04 0,271831 2003:05 -0,237711 2003:06 -0,097254 2003:07 -1,086796 2003:08 0,152231 2003:09 -0,685880 2003:10 0,264577 2003:11 -0,284965 2003:12 -1,154507 2004:01 -0,164507 2004:02 -0,864507 2004:03 -0,334507 2004:04 -0,274507 2004:05 0,225493 2004:06 -0,264507 2004:07 0,185493 2004:08 -0,254507 2004:09 -0,734507 2004:10 -0,514507 2004:11 -0,524411 2004:12 0,775493 2005:01 -0,094507 2005:02 0,155493 2005:03 -0,194507 2005:04 -0,004507 2005:05 -0,784507 2005:06 0,885493 2005:07 0,455493 2005:08 -0,049507 2005:09 -0,184507 2005:10 -0,264507 2005:11 -0,069224 2005:12 -0,634507 2006:01 0,085493 2006:02 -0,104507 2006:03 0,105493 2006:04 0,155493 2006:05 0,265493 2006:06 -0,684507 2006:07 0,415493 2006:08 1,201923 2006:09 0,654289 2006:10 0,471934 2006:11 0,465210 2006:12 1,255493 Cheers Javi
