WebThe confidence bounds will be estimated using the Fisher Matrix method. Confidence Bounds on Time (Type I) The bounds on time are estimated by first solving the reliability equation for time: or: where u = ln(T). The upper and lower confidence bounds on u are estimated from: where: The upper and lower confidence bounds on time are then found by

WebThe Fisher information attempts to quantify the sensitivity of the random variable x x to the value of the parameter \theta θ. If small changes in \theta θ result in large changes in the likely values of x x, then the samples we observe tell us a lot about \theta θ. In this case the Fisher information should be high. how do i change the time zone on my phoneWebDetails.
