Kiefer Wolfowitz NPMLE for Student t non-centrality parameter mixtures
Model: *y_{ig} = mu_{g} + e_{ig}, e_{ig} ~ N(0,sigma_{g}^{2})*
x is the vector of t statistics for all groups, which follows t dist
if *mu_g = 0*, and noncentral t dist if *mu_g \neq 0*,
with *ncp_{g} = μ_g / σ_{g}*.
This leads to a mixture of t distribution with ncp as the mixing parameter.
df (degree of freedom) is determined by the group size in the simplest case.

Data: Sample Observations |

`v` |
bin boundaries defaults to equal spacing of length v |

`u` |

Number of degrees of freedom of Student base density |

`hist` |
If TRUE then aggregate x to histogram weights |

`weights` |
replicate weights for x obervations, should sum to 1 |
