Regression: Testing Assumptions
มุมมอง 565 หลายเดือนก่อน
This video covers the assumptions of linear regression. Use a residual plot and q-q plot to test the assumptions in Excel (Data Analysis Tool Pak) or Python.
Regression: Standard Error of Estimate
มุมมอง 365 หลายเดือนก่อน
Use the standard error of the estimate to create confidence intervals for the mean value of y for a given value of x. Use the standard error of the estimate the sum of squares of x to find the prediction interval for an individual value of y for a given value of x. Use Excel Data Analysis Tool Pak or Python to get the information necessary to build confidence or prediction intervals.

good day. you are awwwwwwwsmmmm. but I finally found a video that I could leave comments, just so that I could contact you and ask a question. your economics graph, how to create supply and demand graph in excel. do you know how to do it with apple iMac? some of the techniques on Microsoft excel don't appear to be accessible in excel iMac. please advise. thank you. chris.
If using a Mac you follow the same procedure. Select scatterplot from the Insert tab. Then right click on the chart and choose Select Data. The menu screen looks different but has the same components (series list, x series, y series, and name). Empty the series list on the left (with - sign). Add each component just like in the video.
Wonderful explanation
awesome
that was awsum explanation..
Wonderful explanation ! Thank you
