Hi,
I get an
"org.apache.commons.math3.exception.MathIllegalArgumentException: not
enough data (17 rows) for this many predictors (293 predictors)"
with the following code : https://pastebin.com/aZ4DXQB3
My class extends OLSMultipleLinearRegression. I have 293 rows of data
with 17 columns.
Is there something I'm missing here? I'm basing my work on the
example @
http://commons.apache.org/proper/commons-math/userguide/stat.html#a1.5_Multiple_linear_regression
Thanks for any guidance.
In Java, the "row" index is the first dimension.
Try
---CUT---
double[][] data = new double[myList.size()][17];
// etc.
---CUT---
HTH,
Gilles
