Mike Strub Challenge
You were recently hired by a forest management company to execute a forest inventory, which has a subsequent objective of finding pole trees within a stand. Using high-density lidar point clouds all dominant and codominant trees were identified. A total of 10,000 trees were found, out of which 500 trees were classified as poles using machine learning techniques. Using Ripley’s K you have found that the pole trees are randomly distributed within the stand. Your specific task is to estimate the field effort needed to harvest the pole trees. The forest management company told you that harvest constraints limit the size of the harvest to 10 pole trees. Consequently, together with the company, you defined the field effort as the total number of trees to be assessed to achieve the 10 pole trees. You have decided to use a sampling without replacement strategy and visually inspects all the trees within a sample. In summary, your approach to estimate the field effort is to sample without replacement from the 10,000 trees and visually inspect all the trees within a sample until 10 pole trees are found. The location of each sample is chosen randomly. Because you want to impress the hiring company you will estimate not only the field effort (i.e., expectation of the number of inspected trees) but also the variability associated with the effort (i.e., the variance of the inspected number of trees). Assessment: 1. To be considered for the challenge, the solution must be submitted by Dec 1, 2022. Please upload your solution as a word or pdf file. 2.
