I just tried to test now some packages which depend on
draw package (
descriptive,
stats). In general, I can get the result but there are some things I can not do (due to the limited Maxima plugin features - I think), or I do not know how to resolve them.
In
stats package, there are nice stat tests but the output is in text format and I do not know how to get that, for instance
(%i1) load( "stats" )$
(%i2) data: [78,64,35,45,45,75,43,74,42,42]$
(%i3) test_mean(data,'conflevel=0.9,'alternative='less,'mean=50);
| MEAN TEST
|
| mean_estimate = 54.3
|
| conf_level = 0.9
|
| conf_interval = [minf, 61.51314273502712]
|
(%o3) | method = Exact t-test. Unknown variance.
|
| hypotheses = H0: mean = 50 , H1: mean < 50
|
| statistic = .8244705235071678
|
| distribution = [student_t, 9]
|
| p_value = .7845100411786889
I struggled with this, but no success.
In
descriptive package, there are quite interesting functions for me, but do not know how to use few stats plots from that package (see the picture). There is no error issued, but there is one step I missed (I suppose). How to export the graph to say SVG and to import it into SMath?.
Regards,
Radovan
