I have a 150 data points for which I would like to plot a normal distribution curve. My output curve is not a single smooth curve but a mesh of traingles and lines approaching a curve. My input and code is as follows: ERh1 = [2.4100 0.7501 0.1456 0.5070 0.7409 0.7514 0.3036 0.3070 ...

A normal curve is the name of the graph of thestandard normal probability distribution, which is what people are (often unknowingly) talking about when they mention any "bell curve" showing where people or other variables stand in relation to some population average or mean. A standard normal ...
Questions about standard normal distribution probability canlookalarming but the key to solving them is understanding what the area under a standard normal curve represents. The total area under a standard normal distribution curve is 100% (that’s “1” as a decimal). For example, the left hal...
To understand this we need to appreciate the symmetry of the standard normal distribution curve. We are trying to find out the area below: But by reflecting the area around the centre line (mean) we get the following: Notice that this is the same size area as the area we are looking ...
A standard normal curve provides both a visual and a numerical representation of how a given variable is distributed across a population when the real-life situation represented by the function is known to have a symmetrical distribution in the population of interest (hence the "bell" shape). Th...
Normalization is a good technique to use when you do not know the distribution of your data or when you know the distribution is not Gaussian (a bell curve). You can normalize all of the attributes in your dataset with Weka by choosing the Normalize filter and applying it to your dataset...
So, it is important to understand how to find a unit vector for a given vector. Visualizing a Unit Vector As mentioned above, a vector can be written in terms of coordinates. In that case, there are three standard unit vectors in a three-dimensional system. These can be written as ...
We’ll use the NORM.DIST function to find the Normal Distribution in Excel. This function needs 4 arguments: x: The data for which we’ll determine the normal distribution. This video cannot be played because of a technical error.(Error Code: 102006) mean: The average value of the ...
Using the Phillips Curve Prominent 20th-century Keynesian economists and government policy buffs such as Paul A. Samuelson and Robert M. Solow believed that the Phillips Curve could be used to monitor the trade-off between inflation and unemployment and keep the business cycle in balance.3 ...
