Re: st: Mkmat doesn't seem to store the observation values correctly? |

My guess would be that your variable Ticker contains the values 8, 9, 2, 1, ... but that these values have labels 441235, 463,13212, 1213, ... You can check that by typing in Stata -list Ticker in 1/10, nolabel-, and see if you than get the values 8, 9, 2, 1....
