LINESTX() is iterative, meaning that it evaluates each row in a table, giving you ultimate control on the data points used (while LINEST() works only with entire columns).
Also, unlike Linest, LinestX can take columns from different tables.
I present step-by-step a real world example where we aggregate the data in the Transactions table (the dependent variable) and use another column from the Calendar table (the independent variable).
