Statistical test to determine if a relationship is linear?

WebApr 2, 2024 · The p-value is calculated using a t -distribution with n − 2 degrees of freedom. The formula for the test statistic is t = r√n − 2 √1 − r2. The value of the test statistic, t, is shown in the computer or calculator output along with the p-value. The test statistic t has the same sign as the correlation coefficient r. WebAug 7, 2024 · I didn't know there was any existing functions to do it, so (a while ago) I just came up with my own intuitive approach. I just assumed the crossover point would be somewhere in the middle of the data. So I tested every point by fitting a line to the data on the left of it, and fitting a line to the data on the right of it.
