WebP-Value is defined as the most important step to accept or reject a null hypothesis. Since it tests the null hypothesis that its coefficient turns out to be zero i.e. for a lower value of the p-value (<0.05) the null hypothesis can be rejected otherwise null hypothesis will hold. In other words, the predictor that holds a lower p-value is ...

WebApr 11, 2024 · However, since the p-value is just a value, we need to compare it with the critical value (⍺): p_value > ⍺ (Critical value): Fail to reject the null hypothesis of the statistical test. p_value ≤ ⍺ (Critical value): Reject the null hypothesis of the statistical test. The critical value that most statisticians choose is ⍺ = 0.05. WebDec 27, 2024 · Simple linear regression is a technique that we can use to understand the relationship between one predictor variable and a response variable..
