Null hypothesis for regression

Web3.6.1 The Null Hypothesis. The null hypothesis is denoted by H 0 H 0, and for the univariate regression can be stated as: H 0: βi = c H 0: β i = c where c c is a constant value, which we are interested in. When testing the null hypothesis, we may either reject or fail to reject the null hypothesis. WebIf you do three independent tests at a 5% level you have a probability of over 14% of finding one of the coefficients significant at the 5% level even if all coefficients are truly zero (the null hypothesis). This is often ignored but be careful.
