Hello all,
I have to produce a lognormal probability plot with logarithmic X axis,
probability Y axis and the fit line (MLE) on it.
I tried both the following options on Linux and Windows platforms of
S-PLUS version 6.2:
1) from command line:
probplot(x, distr="lognormal", mle=T)
The plot would be ok, but I did not find a way to have a log X axis
2) from GUI:
2D graph "PP Normal with Line" selecting "Log-Normal", but once rescaled
and resized the axes, the line disappeares and I don't know how to
redraw it.
Sample data are: 528 559 564 564 603 606 606 616 641 703 739 839
with probabilities: 4.1 12.5 20.8 29.1 37.5 45.8 54.1 62.5 70.8 79.1
87.5 95.8
Anybody can help me?
Thanks in advance.
