A new predator in a community could lead to changes at populations at lower trophic levels, so-called top-down effects. If you consider each of the species in the food web as populations increasing or decreasing, you can imagine a "+" next to a species whose abundance should increase because of the new predator of grabbins; a "-" next to a species whose abundance should decrease; or a "0" if you think a species' abundance will remain the same. It might be useful to draw it up on a paper for yourself. Select the indirect effect that is most likely to be observed if the daggerjaw is introduced as predator on grabbins: Daggerjaw (+), Grabbins (-), Spotted gliders (+); Daggerjaw (+), Grabbins (+), Spotted gliders (+), Umbrella trees (-) Daggerjaw (+), Grabbins (-), Sonar (+), Flamster (-) Daggerjaw (+), Grabbins (-), Ridgehead (+), Torch (-)

The graph of $f$ is shown in the figure. If $\int_a^x f(t)dt$, for what value of $x$ does g(x) have a maximum? y 0 a b c d x There is a similar question in 2008 asking at how many value(s) there are points of inflection. There is a similar graph in 1997 where the graph is said to be the velocity. When is the particle farthest to the right?

Consider a portfolio of: long 6 stocks, short 6 calls (x=15), long 7 calls (x=25), short 15 calls (x=35). Draw the individual payoffs. Remember to show your work and take a photo at the end of the test. The Coordinates of the Portfolio Payoff are: (0,0), (15,90), (25,90), (35,160), (55,0) (0,0), (15,95), (25, 95), (35, 115), (45,0) all are incorrect (0,0), (15,75), (25,75), (35,90), (50,0)

1. Bias vs Variance in Ridge Regression: Consider the problem of estimating the real value parameter $\theta_0$ from the dataset $D$ with $N$ measurements: $y_i = \theta_0 + n_i; \quad n = 1, \dots, N$. (1) Here $n_i; i = 1, 2, \dots, N$ are independent zero-mean Gaussian noise samples of variance $\sigma^2$. Consider the ridge regression estimate specified by $\hat{\theta}_\lambda = \frac{\sum_{n=1}^{N} y_n}{N + \lambda}$ (2) (a) Show that the bias of this estimate is given by $\text{Bias} \left[ \hat{\theta}_{\text{ridge}} \right] = \frac{\lambda \theta_0}{N + \lambda}$.
