Data file

One needs to upload a data file. The data file can be chosen by clicking the Choose File button (it might appear differently for different browsers). We DO NOT save your data file and it is deleted immediately after calculation.

Type of data

The following types of data are allowed:

Select variables

A subset of variables can be used. To use the whole data set, leave this field blank. To select a subset of variables, provide the column numbers that separated by comma (,). For example

1, 2-5, 7-9, 11

will select variables 1, 2, 3, 4, 5, 7, 8, 9, 11

Missing data

Missing data values can be provided. If multiple values are used to denote missing data, they can be separated by comma (,). For example,

-999, -888, NA

will replace all three values above to missing data.
