# p-value

(redirected from Pvalue)

## p-value

The probability, expressed as a number, that a particular effect or association is real or that a given statement or hypothesis is true. If a trial has n possible outcomes and m of these are the desired outcome, then the probability (p) of obtaining the desired outcome is m /n . If all the outcomes are as desired then m = n and p = 1. If none are as desired p = 0. So p is a measure that will alwys range from 0 to 1.

## p-value,

n in statistics, the probability that a random variable will be found to have a value equal to or greater than the observed value by chance alone. This value provides an objective basis from which to assess the relative change in the data.

Thus, even when models are a good fit to the data, a large sample size can result in a large value and a significant pvalue, indicating 'rejection' of the hypothesis that the model has a good fit to the data (Brown, 2006).

If the R-square is small and the Pvalue is large, the relative ratio is white noise.
As it is indicated in the P-value column, the Pvalue in both models is more than %5 (significance coefficient) and consequently H0 hypothesis is accepted in 0.
