Question

6. In class, we saw two different expressions for the Fisher Information (and hence, the CRLB) Here, you will show the two expressions are equal (assuming that you may switch the order of differentiation and integration as needed). As a hint: Differentiatefx(0) d-1 with respect to θ to show that /oo อ In fx (2,0) with respect to θ fx (x:0) dr = 0, Then, differentiate this equation -00

    B2. (a) Suppose θ is an unknown parameter which is to be estimated from a single measurement X, distributed according to some probability density function f(r0). The Fisher information I(0) is defined by de Show that, under some suitable regularity conditions, the variance of any unbi- ased estimator θ of θ is then bounded by the reciprocal of the Fisher information Var | θ 1(8) Note that the suitable regularity conditions, which are not specified here, allow the interchange of...

    Need help with a and b In class we saw how the objective of OLS is to choose coefficients Bo and B, that minimize the squared residuals, summed over all the sample data points, ie. . Since Y Bo+BX,te, we can re-arrange the objective function to: 3 Differentiating equation (1) with respect to Bo and B, leads to the two normal equations: 2(Y-3-3x)-1) 0 i-1 We have two equations, (2) and (3), and two unknowns, Bo and B. Please solve...

    This Exercise contains two classes: ValidateTest and Validate. The Validate class uses try-catch and Regex expressions in methods to test data passed to it from the ValidateTest program. Please watch the related videos listed in Canvas and finish creating the 3 remaining methods in the class. The regular expression you will need for a Phone number is: "^\\(?(\\d{3})\\)?[- ]?(\\d{3})[- ]?(\\d{4})$" and for an SSN: "^\\d{3}[- ]?\\d{2}[- ]?\\d{4}$" This exercise is meant to be done with the video listed in the...
