Calculating the Slope Of A Trendline
So I have a linear graph and created a trendline using the Excel function. I then used the weighted least squares method to create an equation y = b'x + a' using my x and y values as well as their corresponding uncertainties. Would I be able to set the trendline to a specific slope and intercept? If not, is there another way to do this?
I have a simple plot with two points only, and added a trendline which fits with the plotted line. I really need to show the slope of the trend line on the plot. But I don't want to show the equation or anything else.
I am using a plot which should calculated and plot by itself with the change of inputs in the table(somewhere in the page), and need to show that slope value on the plot too.
I can calculate slope in a cell somewhere on the sheet. Is there any way to show the value (calculated somewhere on the sheet) on the plot beside my plotted line.
Either way would work. But I prefer to do it from the trendline.
As a low key user, I can calculate the slope of a line from the x and y values, but I don't know how to determine how good the estimate is. Can
I had a question about the trendline in excel. I just made a trendline and I right clicked "format trendline" and checked "display equation on chart". Unfortunately, the precision of the m and b coefficients (slope and intercept) are nowhere near where I want them to be (only one significant figure). My question is: how do I increase this precision to four or five sig figs? I thought it would have been available somewhere under the "format trendline" option, but I can't find it anywhere.
We have XY (scatter-connected by line) chart.
When I use trendline (polynomial, order of 2) I can ask show up the equation.
But now we would like extract all number from equation shown in individual trendline, and put into a separate file, so we can do detail and complex statistical analysis.
In linear trendline, I can extract number by just computing slope, and intercept.
Can anyone tell me how to extract number of polynomial equation?

Script allows developers to easily embed the functionality of calculating end time from a given start time and span into in 1/2 hour increments.
REQUIRES Cold Fusion 5.0 or MX to run- Uses "CreateTimeSpan" to translate both start time and time span into minutes. That way only a simple addition is required to determine end time.-"TimeFormat" is then used to return the start time and end time back to a HH:MM based time format.-Several of the "TimeFormat" formatting options are provided with this script.
