 ====== Menu: Frequency ======
-In the [[en:manualy:kontext:index|KonText interface ]] menu the item //Frequency// includes the function for creating **frequency distribution**. With this function it is possible to get an overview of the [[en:pojmy:typ|types]] (e.g. of different words) in the search results, along with their frequency. If we wish to find all of the nouns in the genitive case and in the plural form, with this function we can determine which [[en:pojmy:word|words]] occur in this particular case and number and how frequently. It is also possible to use frequency distribution to determine the frequency of both the previous and the following units, calculate [[wp>Lemma_(psycholinguistics)|lemmas]] in the [[en:pojmy:konkordance|concordance]] or determine the distribution of the wanted phenomenon across different text types and their groups (according to the [[en:pojmy:genre|genre]], [[en:pojmy:txtype|txtype]] etc.).

 Frequency distribution includes both custom (general) settings and **quick selection** (both are available at the second level of menu):
-  - **Lemmas** - assesses the query ([[en:pojmy:kwic|KWIC]]) and lists all of the different types of lemmas (attribute [[wp>Lemma_(psycholinguistics)|lemma]]), along with their frequency  ((This option is available only for the corpora that have been lemmatized))
+  - **Lemmas** - assesses the query ([[en:pojmy:kwic|KWIC]]) and lists all of the different types of lemmas (attribute [[en:pojmy:lemma|lemma]]), along with their frequency  ((This option is available only for the corpora that have been lemmatized))
   - **Node forms** - assesses the query ([[en:pojmy:kwic|KWIC]]) and lists all of the different forms (attribute [[en:pojmy:word|word]]), along with their frequency
   - **Doc IDs** - assesses the whole [[en:pojmy:konkordance|concordance]] and lists the text names ([[en:pojmy:atributy_strukturni|structural attributes]] ''name'') in which the wanted phenomenon occurs, along with the frequency of this phenomenon in the individual texts

+==== Text Type frequency distribution ====
 The settings of **Text Type frequency distribution** is located in the second part of the form. It is used only in those cases when the subject of the research depends on what text types do the occurrences in the concordance occur (if we are interested in [[en:pojmy:txtype|txtype]]), [[en:pojmy:srclang|srclang]], [[en:pojmy:medium|medium]] etc.).

 Even in this form we may set the frequency limit, if we wish to restrict the number of results in the list. With the option **Include categories with no hits** it is also possible to display those attributes in the list which did not appear in the concordance. Lemma //dřevo// has not once appeared in the songs (txtype [[en:seznamy:txtype|SON]]). Provided that this option is ticked, txtype SON will appear in the frequency distribution even with a zero frequency.
+==== Two-attribute interrelationship frequency distribution ====
+[{{ :manualy:kontext:2d-fqdist.png?nolink&450|Result of a 2D frequency distribution}}]
+The last type of frequency distribution reflects the interrelationship of two selected attributes (positional as well as structural). As an example, we can look at which nominal adjectives (the so-called short forms, such as rád or schopen) are prominent in three basic text type groups. First, choose the **Two-attribute interrelationship** in the **Frequency** option in the menu (under **Custom**) and select two attributes: first, choose **lemma** (displayed as rows in the table of results), and second, choose **doc.txtype_group** (among Text types, displayed as columns in the table). You can also adjust the minimal value or percentile of [[en:pojmy:frekvence|absolute or relative frequency]].
+After clicking on **Make frequency list**, a table of results is displayed summarizing the number of occurrences of the adjectives in three selected text type groups (fiction, non-fiction and journalistic texts), sorted by frequency. This default setting can be changed: you can re-sort the table by [[en:pojmy:ipm|ipm]], switch the orientation of rows and columns or opt for a list of attribute pairs. If you are an advanced user, you can also try to sort the rows based on three criteria (attribute value, the total of absolute/relative frequency in a row or in a column), set the confidence interval (CI) or temper with the color mapping (for further information, see the help question mark next to the **Color mapping** choice). If you choose the relative frequency display, you can also look at a graph with confidence intervals by clicking on the chart icon next to each variable.
