Release notes Dub Knowledge 2.3.0

Scheduled sampling

Rim based distribution handling (e.g. 50%/50% gender; 50%/50% age categories; 40%/30%/30% area) (not yet available in the scheduled samples)

When creating a new sample in the last screen a new option (take a look at the screen shot, button in the right top corner) called "Rims" is added.
In previous versions, you could only specify the sampling targets based on cell conditions of the entities. The new button "Rims" allows you to specify the sampling target based on rims. You can specify your selection base on one feature and the system will calculate the cell or rims for you.

Specify the sampling targets based on cells

You have defined name of the sample, requirements and cell conditions in order to specify the sampling target based on cell follow this guide:
You will get the following screen. In the limit column, you see how many members you have in each group. Take a look at the image:

For example you have 48 members who are male and in age group 18-25.
In order to specify the sample target set how many percent you need from each group in the "Percent" column. The total number should be always 100:

Select the check box "By participation" if you wish to select members who have not recently participated (longest selection period).
Enter the total number you need in the "Gross N" column (in our case 450) and press button "Distribution" (until you enter a total amount, the button will not be active):

The system will count how many you need from each group. You should press the button "Finish" in order to complete the sample creation.

One extra example to demonstrate what to do in case you are short of members in one of the groups:

You have asked the system to get 30% from cell 1, you only have limit of 48 (see limit column) and according to the system, you need 135 from this group to fulfill the 30% requirement. You can see that in the column "Sample" is number 48 that is all what you have in this group and because you need more the number is red.
In that case press the check box "Cell oversampling" and then the button "Distribution" the amount that you missed in the cell will be spread equally between other cells:

You can also see how the rims are specified click the button rims in the right corner the following screen will be shown:

Press the button Finish to finish the selection and the sample creation.

Specify the sampling targets based on rims

If you wish to specify the sampling target based on rims. Press the button rims and the following screen will be shown:

In the limit column, you see how many members you have in each group. Specify the percentage (how much you need from each group) together it has to be 100:

Enter needed target number (how many you need in our example 450) and press the button "Distribution":

The system will count how many you need from each group automatically. See "Gross N" column. If you press the button “Cells” you will return to the cell specification screen:

You can see that in one cell you did not have enough and because the check box "Cell oversampling" was selected the system automatically get the missing amount from group that had members over.

Possibility to choose a DubInt project (to link with) and auto export after the sample creation, exporting standard features only, also available for scheduled samples, the link must be set when the export is initiated from DubQuest.

The exported samples are highlighted/can be recognized in the list by a green color. To use this feature you need to have the latest version of both applications Dub Interviewer and Dub Knowledge.
Select the project from the drop down menu:

Using delta dates in the date type feature based expressions - relative dates.

When defining requirements it is possible to filter information by their last update:

You have following options to choose from:

Is equal to - select an update date - the system will get only information from this date
Is not equal to - select a date - the system will get all other information except the information from the selected date
After - select a date - the system will get only information after this date
Before - select a date - the system will get only information before this date
Between - select a start and end date - the system will get only information between selected dates
New Is equal to (relative) - select from the following : (you have to specify how many days) days earlier, the current day, (you have to specify how many days) days later - the system will get the requested information.
New Is not equal to (relative) - select from the following : (you have to specify how many days) days earlier, the current day, (you have to specify how many days) days later - the system will get the requested information.
New After (relative) - select from the following : (you have to specify how many days) days earlier, the current day, (you have to specify how many days) days later - the system will get the requested information.
New Before (relative) - select from the following : (you have to specify how many days) days earlier, the current day, (you have to specify how many days) days later - the system will get the requested information.
New Between (relative) - select from the following : (you have to specify how many days) days earlier, the current day, (you have to specify how many days) days later - the system will get the requested information.

Sample selection screen. An aid to help the user to exclude the members from the current selection who participated in previous projects (samples) was added.

Simply press the button "Exclude Sample" and the system will automatically exclude the members who were selected in the defined sample.

Moving (up/down button) selection condition items.

A new moving buttons has been added:

blue arrows - will move only the selected cell condition up or down depends on the position of the cell (in our example the group Age - between - 45,55 would be moved up)
red arrows - will move up or down all cell condition of a feature (in our example it would be Age)

The feature that is on the top of the list has a higher priority the system will start with this cell condition.

New feature type and related operators to support the storage and usage of unicode strings (called WideString).
