p-value

Overview

p-value

p-value is also called probability value, If the p-value is low, the null hypothesis is unlikely, and the experiment has statistical significance as evidence for a different theory, In many fields, an experiment must have a p-value of less than 0,05 for the experiment to be considered evidence of the alternative hypothesis, In short, a low p-value means a higher chance of the null hypothesis

P-value 2 hypothesis, For instance, if the null hypothesis is assumed to be a standard normal distribution N0,1, then the rejection of this null hypothesis can mean either i the mean is not zero, or ii the variance is not unity, or iii the distribution is not normal, In statistics, a statistical hypothesis refers to a probability distribution that is assumed to govern the observed data

Définition de la valeur P — DATA SCIENCE

Si l’investisseur conclut que la p-value est inférieure à 0,05, il existe des preuves solides contre l’hypothèse nulle, En conséquence, l’investisseur rejettera l’hypothèse nulle et acceptera l’hypothèse alternative, À l’inverse, si la p-value est supérieure à 0,05, cela indique qu’il y a peu de preuves contre la conjecture, de sorte que l’investisseur ne rejetterait

p-value definition: “ The p-value is the probability of obtaining test results at least as extreme as the results actually observed, under the assumption that the null hypothesis is correct ,”, — Wikipedia, Part 2: Based on the distribution, data types, purpose, known attributes of our data, choose an appropriate test statistic,

Generalized p-value

In statistics, a generalized p-value is an extended version of the classical p-value, which except in a limited number of applications, provides only approximate solutions,, Conventional statistical methods do not provide exact solutions to many statistical problems, such as those arising in mixed models and MANOVA, especially when the problem involves a number of nuisance parameters,
