You are to create a .dct file (see help infix) containing the dictionary information for the file knkx.txt.
Once this is done, bring in the data. Drop any observations that did not seem to import correctly.
When I say make, it means either make a new variable or keep an existing variable after the infix command:
Make a Date variable - Stata date %td format Make a Time variable - string format Make a Temperature variable - in Fahrenheit (not F*100) Make a Humidity variable - in % (not %*100) Make a Pressure variable - in inches (not inches*100) Make a status variable.
Create a clock variable that contains information for both date and time. (see clock()) Generate a day of week variable.
Find the average, minimum, and maximum temperature by Month and Day of Week so long as your status is okay.
