Excel uses the same formulas that you would find in a standard statistics
book.
Give us some data (no more than 10 (x,y) pairs) and indicate which standard
error you are concerned with (slope, Intercept, etc)

I'm trying to calculate the t-stat but keep getting stumped. I used
LINEST
to get the mean and standard error, but can't seem to replicate how Excel
is
calculating the standard error. Does anyone have the equation that Excel
is
using?
