similar to: Constrained MLE of fixed mean Singh-Maddala distribution

INTRODUCTION TO THE PROBLEM I am trying to fit a distribution to a dataset. The distribution that I am currently considering is the (3-parameter) Singh-Maddala (Burr) distribution. The final model will fix the mean of the distribution to a given value and estimate the remaining parameters accordingly; however, the code provided below ignores this. For this distribution the three parameters

Hi, I've just signed the following petition "Shri. Manmohan Singh, Prime Minister - Government of India : Save RTI Act from Amendments " and wanted to see if you could help by adding your name. Our goal is to reach 15,000 signatures and we need more support. You can read more and sign the petition here:

Hi all Hi list my linux box is CentOS 5.4 it is properly updated I use the [root at r13151 ~]# rpm -qa | grep roundcubemail roundcubemail-0.2.1-1.el5.kb [root at r13151 ~]# roundcubemail , which is contained in the deposit karanbir singh I preferred to continue using the version contained in the official (depot karanbir singh its offcial repositories yes or not ) repositories of CentOS I

You and your crew slowed down the internet last night with all the 5.6 downloads. Congrats!

We want to compute a pseudo R-squared for a model whose parameter estimation was based on maximum likelihood (function likfit, package geoR). I tried to compute the R2 proposed by Maddala (1983) which compare the maximized likelihood for the model without any predictor and the maximized likelihood for the model with all predictors. I got a really low value (0,01%). Did I miss something? Are

Hi, The question is as follows: has anyone coded panel data unit root tests with R? Even the "first generation" tests (see e.g. Levin & Lin 1993; Pesaran, & Smith & Im 1996; Maddala & Wu 1999) would be sufficient for my needs. To my understanding, these are rather easy to code, but as I have taken just my first steps in coding with R, existing code would save me

Greetings, I am using both the lrm() {Design} and glm( , family=binomial()) to perform a a logisitic regression in R. Apart from the typical summary() methods, what other methods of diagnosing logistic regression models does R provide? i.e. plotting an 'lm' object, etc. Secondly, is there any facility to calculate the R^{2)_{L} as suggested by Menard in "Applied Logistic

Dear all, How do I make R show the R-squared (deviance explained by the model) in a logistic regression? Below is how I write my syntax. Basically I want to investigate density-dependence in parasitism of larvae. Note that in the end I perform a F-test because the dispersion factor (residual deviance / residual df) is significantly higher than 1. But how do I make R show the

Hello, 1) I am interested in performing a limited-dependent variable linear regression. By this I mean a classical linear regression, but for the case where the values of the dependent variable cannot vary from -infinity to +infinity, but are truncated and so are between two finite limits L1 and L2. Does R1.7 have this capability? If so what is (are) the relevant command(s)? 2) I am also

Could anyone tell me where can I find some examples of the applications to economics of a Markov chain? Many thanks in advance.

Hi All, I'm new to R and am trying to run a unit root test on the vector "y" (a time series of inflation (i.e. changes in the Consumer Price Index quarter on quarter)). I've run the Augmented-Dickey-Fuller Test below (R's URCA package). It gives me an error that it cannot find the function ur.df unless I comment out the third last line of code (see below). I try to call

Dear useRs, upon request, the VGAM package (currently version 0.7-1) has been officially released on CRAN (the package has been at my website http://www.stat.auckland.ac.nz/~yee/VGAM for a number of years now). VGAM implements a general framework for several classes of regression models using iteratively reweighted least squares (IRLS). The key ideas are Fisher scoring, generalized linear and

Hi, We've got a fairly simple samba setup (no ldap/winbind etc) and until recently everything worked fine (using samba-2.2.5). But after switching to samba-2.2.6 w2k-clients fail to run the netlogon-scripts. When i look at the client it says: logonserver=\\<workstationname> BTW. The output of "nmblookup -S CPB" (to me) seems to say that CPB is the logonserver. querying CPB
