How to Find the Correlation Coefficient With Excel

One simple confusion; now i can i forecast using this regression concept. So if have to predict future, i can use this concept. Many thanks in advance. Hi Svetlana, Thanks for your detailed and well-written article on regression in the Analysis Toolpak and also for mentioning RegressIt as a professional-grade alternative. I'd like your readers to know that RegressIt is free unlike XLSTAT and has many features that are designed to help users learn and apply best practices of regression modeling.

Variables are selected from a list of names rather than by entering coordinates of cell ranges , and there are tools for testing model assumptions, comparing models side by side, and sharing results with others in presentation quality format. The graphs and tables that it produces are far superior to what you get with the Analysis Toolpak, both in terms of design and in terms of the set of options that are available.

RegressIt also includes very detailed built-in teaching notes that can be embedded in the model worksheets, and it has features that help instructors to grade and verify the originality of work submitted by students. Also, unlike the Analysis Toolpak, it has the capability to forecast from a regression model including an option for interactive confidence limits on forecast charts , which addresses the question raised by one of your respondents Syed, post And one more thing: it includes a user-friendly interface with R that allows users to run both linear and logistic regression models in R without writing any code.

This feature allows more sophisticated model testing to be carried out and provides a gentle introduction to the R environment for those without programming experience. I encourage you to mention some of these features to your readers, either in this list of comments or a separate post. Cheers, --Bob.

In the regression graph, the independent variable should always be on the X axis and the dependent variable on the Y axis. If your graph is plotted in the reverse order, swap the columns in your worksheet, and then draw the chart anew. If you are not allowed to rearrange the source data, then you can switch the X and Y axes directly in a chart. October 16, at pm. Jane says:. November 20, at am.
