Nettet25. sep. 2024 · Answer. Excel has a limited set of models that can be used for trend lines to automatically fit curves to data. In later sections we will look at how to we can use calculus to find best fitting curves for other models. Until we develop those techniques, we can make a guess at parameters that will make curves fit. NettetA logarithmic trendline is a best-fit curved line that is most useful when the rate of change in the data increases or decreases quickly and then levels out. A logarithmic trendline can use negative and/or positive values. chemfax flinn scientific inc answers

Bivariate -> scatterplot with confidence ellipse. outside of, say, 95% confidence ellipse is an outlier. Multivariate -> Mahalanobis D2 distance Mark those observations as outliers. Run a logistic regression (on Y=IsOutlier) to see if there are any systematic patterns. flight 1244 frontier
