Created by Kristoffer Magnusson. Share. P-values are often misinterpreted or misused. My goal with this page is to explain p-values through an interactive simulation. WebThe P-value is therefore the area under a t n - 1 = t 14 curve to the left of -2.5 and to the right of the 2.5. It can be shown using statistical software that the P-value is 0.0127 + 0.0127, or 0.0254. The graph depicts this visually. Note that the P-value for a two-tailed test is always two times the P-value for

Only used for non-simulated p-values larger than 2 by 2 tables. Since R version 3.5.0, this also increases the internal stack size which allows larger problems to be solved, however sometimes needing hours. In such cases, simulate.p.values=TRUE may be more reasonable.
