Hi,
I wonder if anyone knows to how to solve this problem. I have a .txt data
and I used -insheet using data1.txt, t- to import it into stata. It shows
that the display type of the variables are string variable. I tried to
convert them into numerical vars. I replaced #.# in -format- command with
#,# as it is European decimal symbol (the comma) used in data. After many
trials, it still gives me strange result. The mean, max and min of the
variables are far away from the truth. For example, the mean for e1 should
be -0,27145726 but stata gives 1,64654, for f1 the true mean is 0,49880390,
in stata is 2,299758 .
Did I make some mistake in the code? Can anyone give me a hand? Many thanks.
