30 lis 2021 · This vignette shows how to use the pvaluefunctions package wich contains an R function to create graphics of p -value functions, confidence distributions, confidence densities, or the Surprisal value (S-value) (Greenland 2019).
To do that, we’ll calculate a number called a p-value. In this lesson, you’ll learn: the four steps common to all hypothesis testing problems. how to conduct a hypothesis test via simulation. what a p-value is, and why it confuses people so much.
Contains functions to compute and plot confidence distributions, confidence densities, p-value functions and s-value (surprisal) functions for several commonly used estimates.
pvaluefunctions: Creates and Plots P-Value Functions, S-Value Functions, Confidence Distributions and Confidence Densities. Contains functions to compute and plot confidence distributions, confidence densities, p-value functions and s-value (surprisal) functions for several commonly used estimates. Instead of just calculating one p-value and ...
In-stead of just calculating one p-value and one confidence interval, p-value functions display p-values and confidence intervals for many levels thereby allowing to gauge the compatibil-ity of several parameter values with the data.
6 sie 2020 · To find the p-value associated with a t-score in R, we can use the pt () function, which uses the following syntax: pt (q, df, lower.tail = TRUE) where: q: The t-score. df: The degrees of freedom. lower.tail: If TRUE, the probability to the left of q in the t distribution is returned.
