xdoc tasks.xml was updated to reflect tasks pertaining to the next planned
release. There tasks were lifted from Phil S. earlier message to commons-dev@ git-svn-id: https://svn.apache.org/repos/asf/jakarta/commons/proper/math/trunk@140850 13f79535-47bb-0310-9956-ffa450edef68

Tasklist is based on an email from Phil Steitz on May 21, 2003
|
||||
<ul>
|
||||
<li>
|
||||
Add quantiles (1,5,10,25,50,75,90,95,99) to all Univaraite
|
||||
implementations and bootstrap confidence intervals to StoredUnivariate
|
||||
implementations.
|
||||
</li>
|
||||
<li>
|
||||
Add higher order moments to StoredUnivariate (UnivariateImpl
|
||||
if possible).
|
||||
</li>
|
||||
<li>
|
||||
t-test statistic needs to be added and we should probably add the
|
||||
capability of actually performing t- and chi-square tests at fixed
|
||||
significance levels (.1, .05, .01, .001).
|
||||
</li>
|
||||
<li>
|
||||
numerical approximation of the t- and chi-square distributions to
|
||||
enable user-supplied significance levels.
|
||||
</li>
|
||||
<li>
|
||||
The RealMatrixImpl class is missing some key method implementations.
|
||||
The critical thing is inversion. We need to implement a numerically
|
||||
sound inversion algorithm. This will enable solve() and also
|
||||
support general linear regression.
|
||||
</li>
|
||||
<li>
|
||||
ComplexNumber interface and implementation. The only tricky thing
|
||||
here is making division numerically sound and what extended value
|
||||
topology to adopt.
|
||||
</li>
|
||||
<li>
|
||||
Bivariate Regression, corellation. This could be done with simple
|
||||
formulas manipulating arrays and this is probably what we should aim
|
||||
for in an initial release. Down the road, we should use the
|
||||
RealMatrixImpl solve() to support general linear regression.
|
||||
</li>
|
||||
<li>
|
||||
Binomial coefficients An "exact" implementation that is
|
||||
limited to what can be stored in a long exists. This should be
|
||||
extended to use BigIntegers and potentially to support logarithmic
|
||||
representations.
|
||||
</li>
|
||||
<li>
|
||||
Newton's method for finding roots
|
||||
</li>
|
||||
<li>
|
||||
Exponential growth and decay
|
||||
</li>
|
||||
<li>
|
||||
Polynomial Interpolation (curve fitting)
|
||||
</li>
|
||||
<li>
|
||||
Sampling from Collections
|
||||
</li>
|
||||
<li>
|
||||
Addition of a Arithmetic Geometric Mean
|
||||
</li>

||||
