RNFL asymmetry has been proposed as a strong indicator of optic neuritis, [7] [8] with one small study proposing that asymmetry of 5–6μm was "a robust structural threshold for identifying the presence of a unilateral optic nerve lesion in MS." [9] Optic neuritis is often associated with multiple sclerosis, and RNFL data may indicate the pace ...
The deviation map reveals the location and magnitude of RNFL thinning relative to a normal value. This normal value was generated as an average of people from various cultures. Defects are colour-coded based on probability of normality (e.g. yellow means that the probability is below 5% of that RNFL at that location is normal).
A mosaic plot, Marimekko chart, Mekko chart, or sometimes percent stacked bar plot, is a graphical visualization of data from two or more qualitative variables. [1] It is the multidimensional extension of spineplots, which graphically display the same information for only one variable. [ 2 ]
Line chart showing the population of the town of Pushkin, Saint Petersburg from 1800 to 2010, measured at various intervals. A line chart or line graph, also known as curve chart, [1] is a type of chart that displays information as a series of data points called 'markers' connected by straight line segments. [2]
The asymptotic distribution can be further characterized in several different ways. First, the central limit theorem states that pointwise, ^ has asymptotically normal distribution with the standard rate of convergence: [2]
How much hair loss is normal? ... the average person actually sheds 50 to 100 strands of hair per day, ... if you have a family history of severe hair loss, or if home remedies do not yield ...
For each step there is a blue tick at the bottom of the graph indicating an observed failure time. The smooth red line represents the exponential curve fitted to the observed data. A graph of the cumulative probability of failures up to each time point is called the cumulative distribution function (CDF).
Normal probability plots are made of raw data, residuals from model fits, and estimated parameters. A normal probability plot. In a normal probability plot (also called a "normal plot"), the sorted data are plotted vs. values selected to make the resulting image look close to a straight line if the data are approximately normally distributed.
