EnvironmentalStats for S-PLUS

What the Users Say

"I've found EnvironmentalStats to be a great resource for producing the results my clients are looking for. The manual itself is a great read and should be recommended to all those involved with the analysis of environmental data."
--Robin Regnier, Central Limit Statistical Consulting

"... it’s an excellent piece of work. I’m especially fond of ... the User’s Manual and the Help module.... It’s really good enough as material for teaching an applied course in environmental statistics."

"Congratulations! I finally had a chance to sit down and read the manual. It is terrific, and exactly what we -- us statistical hydrologists -- have been needing all these years. I am very impressed."

"The goodness of fit plot summary is great (what a time saver)....It is so refreshing to have a statistics software manual that uses datasets with the kind of characteristics we run into."

"[What do I like about EnvironmentalStats for S-PLUS?] Everything! EnvironmentalStats is a great tool in my every day work. I am new to the environmental field and EnvironmentalStats has been a great tool to have for learning current problems and the latest methods applied to those problems. I really feel comfortable using EnvironmentalStats because it provides complete references and I feel that I am not using a black box !"

"As a long-time user of S-PLUS, I am often able to program my own functions. But I never have the time or programming expertise to make the functions yield decent output or allow flexible options. EnvironmentalStats contains the functions I need to do my work, without wasting my client’s money on programming. The output for some of the regular S-PLUS functions is re-formatted so it can be easily inserted into reports. Also, the help files give sound theoretical background on statistical methods, with resources listed for more information."
--Alice Shelly, TerraStat Consulting Group

"... a robust tool which gives documented access to commonly-required statistical methods for environmental problems. Millard knowledgeably reviewed the literature and developed a facile tool which is tied to a powerful statistical engine giving access to alternative methods and automated processes. What more could you want without developing it yourself?"
--Alta Turner, CH2M Hill

"I particularly like your extensive help files and reference list; the functions I’ve used the most in the recent past have been the alternative parameterizations of lognormal distribution (and associated confidence bounds...), the function to calculate power; I like the added distributional options (like the truncated versions, and mixtures of normals and lognormals)...."

"It really is a cool tool."
