What is Estimation: Definition and 205 Discussions
Estimation (or estimating) is the process of finding an estimate, or approximation, which is a value that is usable for some purpose even if input data may be incomplete, uncertain, or unstable. The value is nonetheless usable because it is derived from the best information available. Typically, estimation involves "using the value of a statistic derived from a sample to estimate the value of a corresponding population parameter". The sample provides information that can be projected, through various formal or informal processes, to determine a range most likely to describe the missing information. An estimate that turns out to be incorrect will be an overestimate if the estimate exceeded the actual result, and an underestimate if the estimate fell short of the actual result.
How can I estimate the value of sqrt. of a particular no. which is not a perfect square(e.g. 125) without using the calculator?
Secondly how does the Calculator solve it? Does it use logrithms? If it does how does it solve them?
Can anyone point me to some source code for monte carlo methods for free energy estimation. Standard metropolis/hamiltonian don't work since its the integral not the expectation I'm interested in.
candidates seem to be path sampling/ bridge sampling and annealed importance sampling of which...
now i get the formula I = mr^2 [n2/(n1+n2)] [(gt^2)/(2h) - 1]
where m = mass of the hanging wieght; r = radius; n1 = no. of revolutions before the weight reaches the floor; n2 = no. of revolutions before the flywheel stops; t = time taken for the weight to reach the floor; h = height of...
A typical car with a dummy crashed into a wall, what is a suitable parameter for the head of the crash test dummy(with and without restraints) as a function of time? and how do i estimate the forces acting on the head in the two situations? Thanks a lot :confused:
