Hi, Tom; if you have the time for it, read this here. If not, here is the tip: if you have a text you want to be seen exactly as you type it here, with all linefeeds and monotyped spaces, simply put a [pre] before its first character and a [/pre] after its last character. Your text would look like this:
R2: n, # of data points
To accomplish this, you type: [pre]R2: n, # of data points Hope it helps.

To clear stat registers press: f CLEAR Sigma To enter pairs (xi, yi) press: yi ENTER xi Sigma+
RCL 2: number of elements (pairs)
g x: average x Linear regression y = m * x + b
f L.R. returns b
