Excel 2013 Regression analysis

Regression is a way to find out the “best fit” equation for a set of data. It can help with forecasting and modeling. The linear regression equation will enable you to duplicate the overall data, but it won’t tell you how closely that data is related. An r squared value (the coefficient of determination) tells you how closely the linear regression line matches the dataset.

Excel 2013 Regression analysisIf you’re taking a stats class and you want to perform Excel 2013 regression analysis, you’re probably looking to find the equation and r-squared. The Data Analysis tab does have an option for regression, but that is an option you’ll want to take only if you’re performing hypothesis testing. The reason? Data analysis returns a whole slew of results that you don’t want or need. The simplest way to perform Excel 2013 regression analysis is with an Excel scatterplot.

Excel 2013 Regression analysis: Steps

Step 1: Select your data. To select data, click the top left corner of your data set and then drag the cursor down to the bottom right.

Step 2: Select the “Insert” tab.

Step 3: Select “Scatter” in the Charts area and then click the first scatter graph (a simple scatter graph).

Step 4: Click a data point on the graph then right click.

Step 5: Click “Add trendline” from the drop down menu.

Step 6: Scroll to the bottom of trendline options. Trendline Options is at the far right of the screen.

Step 7: Click the check boxes for “Display R-squared value on chart” and “Display equation on chart.” R-squared and the regression equation will appear on the chart.

That’s it!

    Is it okay to find the regression line using the SLOPE and INTERCEPT formulas?

    From there I can use the results of those formulas to make inputs in mx+b fashion, and they seem to work most of the time; using the CORREL formula to verify accuracy.

    Am I totally missing the point on using that method?

    That’s certainly one other way to do it. I’m curious as to why it only works most of the time? Seems to me it should work ALL of the time.

    I want to make multiple regression like y = Ax1+Bx2+CX3+constant using Droitereg function. With my Excel2013 it work only for simple linear regression like y = Ax+b. Why it don’t work. I got the message “Too many arguments”?
