Re: [amelia] Amelia Development Version not installing

Thanks for your replies. I have tried using the stable version the imputation gets completed about 50% of the time but I get the following output and error the rest of the time: -- Imputation 1 -- setting up EM chain indicies 1(3338) 2(3134) 3(2490) 4(1474) 5(665) 6(302) 7(159) 8(96) 9(72) 10(46) 11(24) 12(18) 13(14) 14(7) 15(5) 16(2) 17(2) 18(2) 19(2) 20 (1) 21(1) 22(1) 23(1) 24(1) 25(1) 26(1) 27(1) 28(1) 29(1) 30(1) 31(1) 32(1) 33(1) 34(1) 35(1) 36(1) 37(1) 38(1) 39(1) 40 (1) 41(1) 42(1) 43(1) 44(1) 45(1) 46(1) 47(1) 48(1) 49(1) 50(1) 51(1) 52(1) 53(1) 54(1) 55(1) 56(1) 57(1) 58(1) 59(1) 60 (1) 61(1) 62(1) 63(1) 64(1) 65(1) 66(1) 67(1) 68(1) 69(1) 70(1) 71(1) 72(1) 73(1) 74(1) 75(1) 76(1) 77(1) 78(1) 79(1) 80 (1) 81(1) 82(1) 83(1) 84(1) 85(1) 86(1) 87(1) 88(1) 89(1) 90(1) 91(1) 92(1) 93(1) 94(1) 95(1) 96(1) 97(1) 98(1) 99(1) 100 (1) 101(1) 102(1) 103(1) 104(1) 105(1) 106(1) 107(0) error: Mat::operator(): index out of bounds terminate called after throwing an instance of 'std::logic_error' what(): Mat::operator(): index out of bounds For the same dataset, the imputation ran smoothly on the development version, which is why I was asking about the development version. Not sure what the source of the error is. Any suggestions you have to deal with this would be very useful.

However since the last two days an installation error pops up when trying to install using the following command: install.packages("Amelia", repos="http://r.iq.harvard.edu", type = "source") The error: Warning: unable to access index for repository http://r.iq.harvard.edu/src/contrib: cannot open URL 'http://r.iq.harvard.edu/src/contrib/PACKAGES' Warning message: package ‘Amelia’ is not available (for R version 3.2.3) Error in library("Amelia") : there is no package called ‘Amelia’ Execution halted Would be great if the permissions could be restored so we can continue using the development version.

We have a fix for it in the development version of Amelia. You can find installation instructions for that version here: https://github.com/IQSS/Amelia<https://urldefense.proofpoint.com/v2/url?… We will be submitting this development version to CRAN in the upcoming weeks.

The subset used in the analysis has 64 variables. I only kept factor variables with 2 to 10 levels in the subset, but when I run the amelia command I get the following error: **** Error in `contrasts<-`(`*tmp*`, value = contr.funs[1 + isOF[nn]]) : contrasts can be applied only to factors with 2 or more levels **** On the other hand the amelia code runs if I specify "incheck = FALSE" in the command options. I am also able to do multiple imputation on this dataset using other R software but am keen to work with Amelia, since I want to utilize the TSCS aspect of multiple imputation that the software provides. Could you shed some light on why I am seeing the error above and also if the imputation with errors suppressed is reliable?
