Sufficient conditions are given for the existence, uniqueness and finite-dimensional approximation of the solution to a first-order infinite-dimensional vector differential equation. Given a suitable ...

Rounding to the nearest whole number. What is estimating? Use approximation through rounding to estimate answers to calculations. Rounding numbers (decimals) Rounding numbers to a given number of ...

We study in detail the log-linear return approximation introduced by Campbell and Shiller (1988a). First, we derive an upper bound for the mean approximation error, given stationarity of the log ...
