I have to do a multiple regression in excel with regression tool(with 4
variables). I successfully got it to work, and a lot of charts and
graphs are out putted. My question has to do with one of the charts.
One of the charts has columns labled "Coefficients", what does this
mean? I thought it was the slop (b) of the least squares line for each
variable. However some of the values in the coefficients are negative,
but if you look at the output charts the correlation go in a positive
direction for these variables. another question i have is on the graphs
on noticed that there are two types output graphic in excel what are the
differences?
