See image for likelihood.
Differentiate the log-likelihood with respect to β to obtain the equation that we want to solve.
What is the analytical solution to this equation?
![**Numerical Maximization:** Suppose we want to maximize this likelihood with respect to \( \beta \):
\[
L(\beta | y_1, \ldots, y_n) = \prod_{i=1}^{n} \frac{1}{\beta} e^{-y_i / \beta}
\]
This formula represents the likelihood function for given data points \( y_1, y_2, \ldots, y_n \). The goal is to find the value of \( \beta \) that maximizes this function. The expression involves a product of \( n \) terms, each including the exponential function \( e \) and the variable \( \beta \), which needs numerical methods for efficient computation in practical scenarios.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd778ad93-bdd9-4703-922d-f708dcbd5bfa%2F85b89fe4-db3c-4a57-a3d7-7cd33933ab50%2Fdg1j1t_processed.png&w=3840&q=75)
