    • +
+ + + + Tasklist is based on an email from Phil Steitz on May 21, 2003 +
    +
  • + Add quantiles (1,5,10,25,50,75,90,95,99) to all Univaraite + implementations and bootstrap confidence intervals to StoredUnivariate + implementations. +
    • +
  • + Add higher order moments to StoredUnivariate (UnivariateImpl + if possible). +
    • +
  • + 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). +
    • +
  • + numerical approximation of the t- and chi-square distributions to + enable user-supplied significance levels. +
    • +
  • + 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. +
    • +
  • + ComplexNumber interface and implementation. The only tricky thing + here is making division numerically sound and what extended value + topology to adopt. +
    • +
  • + 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. +
    • +
  • + 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. +
    • +
  • + Newton's method for finding roots +
    • +
  • + Exponential growth and decay +
    • +
  • + Polynomial Interpolation (curve fitting) +
    • +
  • + Sampling from Collections +
    • +
  • + Addition of a Arithmetic Geometric Mean +
