Statistics 100A Homework 4 Solutions
First, note that we have a finite number of trials, n = 4 (although the game goes on forever, we are only concerned with the first 4 balls.) Each trial is a Bernoulli trial that is, each trial has only one of two outcomes: white and not white. Define a success as the event that a white ball is drawn. Then the probability of success p is p = 12 . Since each ball is replaced after it is drawn, we...

1. For a discrete process convolution model with unknown kernel parameters, linear trend, and inverse gamma priors on the variance parameters, write the full conditionals and indicate how to perform the calculations needed to sample from them. In matrix form, we have y = X(s)β + K(s, ψ)w + , where x(s i) is the i-th row of X(s), K ij = k ij = k(s i − u j ; ψ). With the assumption that p(w, β, τ...

1. Prove the results about the smoothness of the members of the Matèrn family. Proof. From the class we know that for small values of τ , we have K ν (τ) ≈ Γ(ν)2 ν−1 τ −ν. Also, for the derivatives we have that d dτ (τ ν K ν (τ)) = −τ ν K ν−1 (τ). If the Matèrn family has the correlation function ρ(τ) = 1 Γ(ν)2 ν−1 τ ν K ν (τ), then ρ (τ) = −1 Γ(ν)2 ν−1 τ ν K ν−1 (τ) Note that K ν (τ) = K −ν (τ...

The main aim of this study was to determine students' perceptions toward web-based versus paper-based homework and identify any differences based on homework performance score and grade point average. A 21-item perception of online vs. paperbased homework survey was administered to 103 students (54 were male and 49 were female) in general physics-1 classes. Results of the study indicated that t...
