In Deducer: A Data Analysis GUI for R

Confidence interval for the Non-centrality parameter of Non-central chi-squared distribution

1	chi.noncentral.conf(chival,df,conf,prec=.00001)

`chival`	The observed Chi-Squared value
`conf`	The confidence level (e.g. .95)
`df`	Degrees of freedom
`prec`	Precision of estimate

A 2X2 matrix whose rows represent the upper and lower bounds, and whose columns represent the parameter value and upper tail percentiles.
