How to interpret maximum likelihood estimates
WebThe maximum likelihood estimator of the parameter solves In general, there is no analytical solution of this maximization problem and a solution must be found numerically … WebWith the RI beam, however, the profile of the dose was still different from that of the activity. Therefore interpretation from activity distribution to dose distribution is necessary to confirm the irradiation field precisely. In this paper, we developed a method of estimating the dose distribution from PET measurements.

WebIn the case of the alternative model, the maximum likelihood estimate ˆθ^θ is the maximum value. Now, assuming for simplicity that the data are coming from a normal distribution, the numerator of the likelihood ratio statistic is: lik(θ = μ0) = 1 (σ√2π)nexp( − 1 2σ2 n ∑ i = 1(Xi − μ0)2) For the denominator, the MLE ˉX ¯X is taken as μμ: WebMentioning: 16 - International audienceSpeckle phenomenon in synthetic aperture radar (SAR) images makes their visual and automatic interpretation a difficult task. To reduce strong fluctuations due to speckle, total variation (TV) regularization has been proposed by several authors to smooth out noise without blurring edges. A specificity of SAR images …
