The value depends on how long the company expects to use the asset and how hard the asset is used. For example, if a company sells an asset before the end of its useful life, a higher value can be justified.

WebJan 25, 2024 · Random events have two characteristics: a value and a probability. It's clear in the discrete case; a normal die has a 1/6 probability of rolling each of one through six. You can find the expected value of one roll, it's $\frac{1+2+3+4+5+6}{6}$. But you can't find the expected value of the probabilities, because it's just not a meaningful question. WebExpected mean squares. Imagine taking many, many random samples of size n from some population, estimating the regression line, and determining MSR and MSE for each data set obtained. It has been shown that the average (that is, the expected value) of all of the MSRs you can obtain equals: \(E(MSR)=\sigma^2+\beta_{1}^{2}\sum_{i=1}^{n}(X_i-\bar ...
