JXG.Math.Statistics
Functions for mathematical statistics. Most functions are like in the statistics package R.
Method Detail
<static> {Array|Number} JXG.Math.Statistics.abs(arr)
Determines the absolute value of every given value.
Parameters:
{Array|Number} arr
Returns:
{Array|Number}
<static> {Array|Number} JXG.Math.Statistics.add(arr1, arr2)
Adds up two (sequences of) values. If one value is an array and the other one is a number the number is added to every element of the array. If two arrays are given and the lengths don't match the shortest length is taken.
Parameters:
{Array|Number} arr1
{Array|Number} arr2
Returns:
{Array|Number}
<static> {Array|Number} JXG.Math.Statistics.div(arr1, arr2)
Divides two (sequences of) values. If two arrays are given and the lengths don't match the shortest length is taken.
Parameters:
{Array|Number} arr1
Dividend
{Array|Number} arr2
Divisor
Returns:
{Array|Number}
<static> JXG.Math.Statistics.divide()
Deprecated:
Use JXG.Math.Statistics#div instead.
<static> {Number} JXG.Math.Statistics.max(arr)
Extracts the maximum value from the array.
Parameters:
{Array} arr
Returns:
{Number} The highest number from the array. It returns NaN if not every element could be interpreted as a number and -Infinity if an empty array is given or no element could be interpreted as a number.
<static> {Number} JXG.Math.Statistics.mean(arr)
Determines the mean value of the values given in an array.
Parameters:
{Array} arr
Returns:
{Number}
<static> {Number} JXG.Math.Statistics.median(arr)
The median of a finite set of values is the value that divides the set into two equal sized subsets.
Parameters:
{Array} arr
The set of values.
Returns:
{Number}
<static> {Number} JXG.Math.Statistics.min(arr)
Extracts the minimum value from the array.
Parameters:
{Array} arr
Returns:
{Number} The lowest number from the array. It returns NaN if not every element could be interpreted as a number and Infinity if an empty array is given or no element could be interpreted as a number.
<static> {Array|Number} JXG.Math.Statistics.mod(arr1, arr2, math)
Divides two (sequences of) values and returns the remainder. If two arrays are given and the lengths don't match the shortest length is taken.
Parameters:
{Array|Number} arr1
Dividend
{Array|Number} arr2
Divisor
{Boolean} math Optional, Default: false
Mathematical mod or symmetric mod? Default is symmetric, the JavaScript % operator.
Returns:
{Array|Number}
<static> {Array|Number} JXG.Math.Statistics.multiply(arr1, arr2)
Multiplies two (sequences of) values. If one value is an array and the other one is a number the number is multiplied to every element of the array. If two arrays are given and the lengths don't match the shortest length is taken.
Parameters:
{Array|Number} arr1
{Array|Number} arr2
Returns:
{Array|Number}
<static> {Number} JXG.Math.Statistics.prod(arr)
Multiplies all elements of the given array.
Parameters:
{Array} arr
An array of numbers.
Returns:
{Number}
<static> {Array} JXG.Math.Statistics.range(arr)
Determines the lowest and the highest value from the given array.
Parameters:
{Array} arr
Returns:
{Array} The minimum value as the first and the maximum value as the second value.
<static> {Number} JXG.Math.Statistics.sd(arr)
Determines the standard deviation which shows how much variation there is from the average value of a set of numbers.
Parameters:
{Array} arr
Returns:
{Number}
<static> {Array|Number} JXG.Math.Statistics.subtract(arr1, arr2)
Subtracts two (sequences of) values. If two arrays are given and the lengths don't match the shortest length is taken.
Parameters:
{Array|Number} arr1
Minuend
{Array|Number} arr2
Subtrahend
Returns:
{Array|Number}
<static> {Number} JXG.Math.Statistics.sum(arr)
Sums up all elements of the given array.
Parameters:
{Array} arr
An array of numbers.
Returns:
{Number}
<static> {Number} JXG.Math.Statistics.variance(arr)
Bias-corrected sample variance. A variance is a measure of how far a set of numbers are spread out from each other.
Parameters:
{Array} arr
Returns:
{Number}
<static> {Number} JXG.Math.Statistics.weightedMean(arr, w)
Weighted mean value is basically the same as JXG.Math.Statistics#mean but here the values are weighted, i.e. multiplied with another value called weight. The weight values are given as a second array with the same length as the value array..
Parameters:
{Array} arr
Set of alues.
{Array} w
Weight values.
Throws:
{Error}
If the dimensions of the arrays don't match.
Returns:
{Number}
