A regression is performed to determine the effect of work experience (WorkExp, in years) on the number of weeks it takes unemployed people to find a new job (Weeks). Based on the outputs presented, what is the correct conclusion?

ByAdmin August 21, 2021August 21, 2021

The ?-squared value suggests that WorkExp is not an important influence factor, and that there must be other more relevant influence factors.

WorkExp has a significant impact on Weeks.

Although we observe a relationship between the two variables, the evidence in the data is not significant, indicated by the high ?-squared value.

Although we observe a relationship between the two variables, the evidence in the data is not significant, indicated by the small ?-value.

Let qq be the original query vector, D_R=\{P_1,…,P_n \}DR={P1,…,Pn} be the set of positive document vectors, and D_N=\{N_1,…,N_m\}DN={N1,…,Nm} be the set of negative document vectors. Let q_1q1 be the expanded query vector after applying Rocchio on D_RDR and D_NDN with positive parameter values \alphaα, \betaβ, and \gammaγ. Let q_2q2 be the expanded query vector after applying Rocchio on D_RDR and D_NDN with the same values for \alphaα, \betaβ, but \gammaγ being set to zero. Which of the following is correct?
