NettetFirst, the area under the curve equals 1. Second, the probability of any exact value of X is 0. Finally, the area under the curve and bounded between two given points on the X … NettetA, B and D are also linear with Y (holding everything else constant) so the model is linear. But if you graph Y vs. X for a polynomial model, you'll almost always see a curve, not a line (it depends on what values you assign to A-D. So linear describes the model, not the graph of X vs. Y. If the model is not linear, then it is nonlinear .

Nettet28. aug. 2024 · The t -distribution, also known as Student’s t -distribution, is a way of describing data that follow a bell curve when plotted on a graph, with the greatest number of observations close to the mean and fewer observations in the tails. It is a type of normal distribution used for smaller sample sizes, where the variance in the data is unknown.
