Description: fit_ML_normal - Maximum Likelihood fit of the log-normal distribution of i.i.d. samples!.
Given the samples of a log-normal distribution, the PDF parameter is found
fits data to the probability of the form:
p(x) = sqrt(1/(2*pi))/(s*x)*exp(- (log(x-m)^2)/(2*s^2))
with parameters: m,s
format: result = fit_ML_log_normal( x,hAx )
input: x - vector, samples with log-normal distribution to be parameterized
hAx - handle of an axis, on which the fitted distribution is plotted
if h is given empty, a figure is created.
output: result - structure with the fields
m,s - fitted parameters
CRB_m,CRB_s - Cram?r-Rao Bound for the estimator value
RMS - RMS error of the estimation
type - ML - fit_ML_normal - Maximum Likelihood fit of the log-normal distribution of i.i.d. samples!.

Description: Large-scale variations caused by shadowing of obstacles are shown to follow a log-normal distribution [17][18][19], which means that when measured in dB they follow a Gaussian distribution. Consequently shadowing effects are usually incorporated into path loss estimates by the addition of a zero-mean Gaussian random variable, with standard deviation σ: N(0,σ), were σ is often estimated by empirical measurements. Commonly accepted values for σ are between 6 dB and 12 dB. Measured values of σ itself seem to display Gaussian distribution as well, in their variations from one area to another, and depend on the radio frequency, the type of environment (rural, suburban, or urban), base station and subscriber station height.

Description: 频发故障的寿命分巧拟合,频发故障的部件，可以基于往大量的维修经验以及相关可靠性寿命试验中测得的结果来判断这类寿命的分布类型，常常有威布尔分布类型、对数正态分布类型，以及指数分布类型等。因此本程序可以根据故障数据输入判断出该数据属于哪一种寿命分布。(Frequent failure of the life of the split fit, frequent failure of the components, can be based on a large number of maintenance experience and related reliability life test results measured to determine the type of distribution of such life, often Weibull distribution type, Logarithmic normal distribution types, and exponential distribution types. So the program can be based on fault data input to determine the data belongs to which life distribution.) Platform: |
