Description
Sets the loop counter to zero for the first input.
Checksum and length: 5AB9 24
Defines the beginning of the input loop.
Adjusts the loop counter by one to prompt for input.
Stores loop counter in X so that it will appear with the
prompt for
X.
Displays counter with prompt and stores X input.
If flag 0 is set . . .
. . . takes the natural log of the X–input.
Stores that value for the correction routine.
Prompts for and stores Y.
If flag 1 is set . . .
. . . takes the natural log of the Y–input.
Accumulates B and R as x,y–data pair in statistics registers.
Loops for another X, Y pair.
Checksum and length: C95E 57
Defines the beginning of the "undo" routine.
Recalls the most recent data pair.
Deletes this pair from the statistical accumulation.
Loops for another X, Y pair.
Checksum and length: AB71 15
Defines the start of the output routine
Calculates the correlation coefficient.
Stores it in R.
Displays the correlation coefficient.
Calculates the coefficient b.
If flag 1 is set takes the natural antilog of b.
