I want to make an analysis under implied weights

From TNT

This is a quick guide to perform an analysis under implied weights. For a more technical explanation look under Manual/Searches/Implied weighting.

Setting Implied weights (menu version)

1. Go to menu path: Settings/Implied weighting.

2. Check "using implied weights" and set the current k value.

3. If implied weights is on, then a check appears in front of the entry Implied weighting in the menu Settings.

4. Repeat from (1) if you want to change the k value.

5. To turn off implied weights go to menu Settings / Implied weights and check "based on prior weights only".

6. If Implied weights is off, there is no check on the entry Implied weighting in the menu Settings.

Setting Implied weights (command line)

1. Type piwe = N; where N is the value of k.

---

Example: setting implied weights with k = 3.

2. To check if implied weights is on, type piwe;

---

Example: Check implied weights status.

3. Repeat from (1) if you want to change the k value.

4. To turn off implied weights type piwe -;

---

Example: Turn implied weights off.

5. To check if implied weights is off, type piwe;

Setting an user defined function (command line only)

1. Before load the data turn implied weights on (using the menu, or the command line)

2. After data is loaded use piwe [ and type the value of the difference in fit between 0-1 extra-step, 1-2 extra-steps, 2-3 extra-steps (look under Manual/Searches/Implied weighting for a full explained example).

---

Example: Setting a user defined function.

3. To check if user function is on, type piwe; to check actual values used for TNT type piwe [;

---

Example: Look for actual function values.

4. To turn off the user function type piwe ]; This turn off the user function and uses the default function (i.e. standard implied weight analysis), that is, implied weights continue on.

5. To turn off implied weights type piwe -;

6. To turn on implied weights type piwe =; If you not turn off the user function, then the user function is on.

For example, the sequence of commands

piwe [ 1.00 0.80 0.70 ;
piwe -;
piwe = 4;

Use the user function, instead the default function with k = 4. The correct sequence must be

piwe [ 1.00 0.80 0.70;
piwe ];
piwe -;
piwe =4;
