Multi-Linear Regression OLS in java ( Weka)
Hi there,
I was just wanting confirmation that this function: weka.classifiers.functions.LinearRegression, uses the OLS algorithm, closed form.
I found from this link below:
http://forums.pentaho.com/showthread...oefficients%29
Also I have been trying to find a sample example in java of Multi-Linear Regression that not only returns the coefficients, but also returns many more statistics such as,
standard error of the coefficients, t-statistics of coefficients, p-values, F-test value, residuals, R.
On the web I only found one example which just returns the coefficients and nothing more.
Hope someone knows of some examples or resources on Multi-Linear Regression in java using Weka.
Regards.

How to set maximum row or record to be display in every page of the report? Let say there are 30 record, I want it to be display only 10 record in each page ..so it will become 3 page display in my report. Can Pentaho 5.1 do it or not? Any idea or advice?

Merging streams with different columns
Hi there, I'm starting with stream [col A, col B]. Based on filter on [col A], I merge I merge some rows [col A=x] with other set [col C] and calculate left over [col A!=x] in another [col fxA]. Then I want to UNION these streams again which I can't because one stream has [col A, B, C] and the other has [col A, fxA]. I don't mind null values - all I want not to manually adjust the order and names of the columns. I could do this in Excel PowerQuery. Is there a way of doing it in Pentaho?

Appending an excel having formula
Hi,
I have defined an excel template with formulas for few cells, and I want to update each day the generated report based on that template. But the problem is that, after 1st report is created, next day when it gets updated, it starts writing at the row where the formula is not present, i.e. it skips those blank rows upto which formula was defined.
Any suggestion as how this can be fixed??
Thanks in advance for your support.

Problems when trying to save Log - Urgent
Hi everyone,
I'm currently involved in a project in which our main goal is to analyze Kettle log step by step in order to make some optimizations. What I would like to know is if there's some way to save the log of each step to a relational table with the time interval that the step took. I know you can save the step log and I've already tried it but the only timestamp associated is not what I'm looking for.
Also I'm running Kettle on a Mac OS and can't find my log files (the next step is to try to save the log file).
If anyone can help me with this I would appreciate :) Thanks!

What Java versions are required for which versions of Pentaho?
I am looking to make an upgrade from PDI 4.2 to 6.0 (or some other newer version, should 6.0 have problems). If I upgrade the current JRE from 6 to 7, will the Pentaho 4.2 still work? (More specifically, do both 4.2 and 6.0 work with JRE7?)
I am assuming that installing JRE 8 will break the use of PDI 4.2, so I am wondering if installing JRE7 can allow some concurrent-running.
Thanks all.

Cannot run Pentaho
Hello,
I am not sure if I post my question in right place here but I do it anyway [IMG]file://localhost/Users/Mehran/Library/Group%20Containers/UBF8T346G9.Office/msoclip1/01/clip_image002.png[/IMG].
I have downloaded Pentaho and try run it in my computer but not success. I have edited the Spoon.bat file as below, but still I cannot run Pentaho:
Edit the Spoon.bat file and:
• Replace in the last line "start javaw" with only "java".
• Add a "pause" in the next line.
• Save and try it again.
When I run the program, the cmd windows opens and disappear then nothing happens. What is the problem and how can I resolve it?

Get the Nth larger value
Hi,
in Excel there's a fórmula that is called Large. It has two inputs: the interval to look and a constant "k", where "k" is the Nth value to get. I mean, with this formula is possible to get the Nth larger value in a stream. There's an step that does something like these? Maybe with Java Script Value step or Group by?

IF-clause in PDI
Hello,
i want to implement some kind of if-clause in PDI.
I got three parameters in the transformation which are all strings and now i want to check whether the combined length of all three parameters is smaller than 20. At this condition the program should decide how it operates next (which step it takes next, e.g. creates a new table or on the other hand adds a new column - that doesn't matter for now).
So is there any possibility to design such an "if-clause" in PDI?
Best regards
Thomas

Trouble with the "Insert data from step" option
This is probably a very elementary question but I've reviewed the wiki and can't get this to work to save my life.
Step 1 = Import from a .csv file that has a column of data containing software hash values from Microsoft SCCM
Step 2 = Set values where I'm simply trying to get the column which is SoftwareHash
Step 3 = Table Input
In the table input I have a Select statement with a bunch of joins which includes a join to a table that has SoftwareHash values. When I preview the output of that SQL Select statement I see what I would expect. But when I try to add the following, I don't get any results and just a big error
Here is an example:
SELECT * FROM v_GS_Computer_Systems
WHERE Isobsolete = '0'
AND SoftwareHash = ?
What I thought this would do is look at the previous step of set values and replace the ? with a value from the first step. But I must be missing something. Any help is greatly appreciated. This is my first attempt doing anything with SPOON.
