<p>(if you are not familiar with Zipf’s law, you may wish to look at the screenshots first, as they provide a visual context for the following)</p>
<p>Zipfstats is built around Zipf’s law, which states that given some corpus (in this case, a post/page) of natural language, the frequency of any word is inversely proportional to its rank in the frequency table. In a perfect Zipfian distribution, this would mean that the most frequent word in the corpus will occur twice as often as the second most frequent word, three times as often as the third most frequent word and so on. Any given real world corpus, if large enough, will tend to approximate a Zipfian distribution (this also works for cities as ranked by population, though that observation is less useful in this context).</p>
<p>The Zipfstats widget analyzes and reports word frequency by rank of a given single post or page (aka the corpus). The widget shows a small graph that plots the actual frequency-rank distribution of the content against a perfect Zipfian distribution, thus illustrating the degree to which the content follows Zipf’s law. It also provides for a table of the top-ranked words.</p>
<p>Zipfstats only analyzes the core content of a given post/page. It does not incorporate comments into its calculations. By default, it removes shortcode-generated content from its analysis, though you may optionally enable it. Filters, other than do_shortcode() (in the aforementioned case), are not affected in terms of the analysis. Actual output of the original content is unchanged, regardless of the options selected.</p>
<p>Options</p>
<ul>
<li>Show Only to Admin Users (default = on): only admin-level users see Zipfstats output. If unchecked, all users, logged or non-logged, will see it.</li>
<li>Strip Shortcode Content from Analysis (default = on): skips processing of and removes all shortcodes from the content of the post or page prior to analysis. Actual content remains unaffected.</li>
<li>Include Graph (default = on): Display a log-log plot of word frequency data against a perfect Zipf distribution</li>
<li>Include Word Frequencies (default = on): in addition to the Zipf plot, this option includes a table of the top n words in rank order as well as the frequency of their occurrences in raw terms. A clickable header allows the user to toggle between showing/hiding the wordlist.</li>
<li>Expand Word Frequency Table by Default (default = on): if expand is selected, the wordlist (if also selected) will be displayed on initial page load. Unchecked, the user will have to toggle its display manually via a clickable header.  </li>
<li>Number of Words to Show (default = 10, max 25): this determines the number of words to appear in the “top n” wordlist table, if the latter is enabled. This option does not affect any calculations.</li>
</ul>
<p>Some things to note:</p>
<ul>
<li>No site data is modified or stored. Widget results are generated on the fly. Zipfstats does not directly initiate any database activity, but merely uses the the $post object to analyze content, and the WordPress widgets API to store a handful of options.</li>
<li>Post/page content will be displayed as normal. If the widget is added to a sidebar, it will appear where placed, again, without any change to existing post/page content.</li>
</ul>
<h4>Future Enhancements</h4>
<ul>
<li>Add site-wide/category-wide/author-wide analyses</li>
<li>Add to admin post/page edit</li>
<li>Add recommendations to better approximate a Zipfian distribution</li>
</ul>


Zipfstats

Zipfstats provides a widget plotting the frequency each word appears in a post/page and its rank (most frequent->least) against a Zipf distribution …

<p>The Anomify plugin sends selected performance metrics about your WordPress site to the Anomify.ai service for anomaly detection and alerting.</p>
<p>After ingesting data we learn normal patterns, detect any unusual behaviour, alert on anomalies in real time, and constantly feed back to improve the model.</p>
<p>You will need to obtain an API key and data URL from <a href="https://anomify.ai/" rel="nofollow ugc">Anomify AI</a> before the plugin can be enabled. Anomify has a free Developer account which allows up to 100 metrics.</p>
<h3>Intro</h3>
<p>Anomify AI is a UK based anomaly detection company for real time time-series data. Using machine learning and multi-stage analysis we enable organisations to react quickly to the changing health of their data at scale.</p>
<p>We provide a cost-effective anomaly detection solution, which can be deployed flexibly via the cloud or on-premise.</p>
<p>Anomify employs a semi-supervised system model that allows domain experts to directly train the system and continually improve its performance and usefulness.</p>
<h3>Native Metrics</h3>
<ul>
<li>content.comment.added.{approved|not-approved|spam}</li>
<li>content.{post_id}.deleted</li>
<li>content.{post_id}.updated</li>
<li>content.{post_type}.status.transition.{new_status}</li>
<li>login.fail</li>
<li>login.success</li>
<li>php.exception</li>
</ul>
<h3>Integration with other WordPress plugins</h3>
<p>Anomify can integrate with certain other plugins to send metrics describing their performance to Anomify which wll automatically detect anomalies.</p>
<p>The Anomify WordPress plugin can detect anomalies on metrics generated from certain other plugins.</p>
<p>To enable a third-party plugin integration, first install and activate the plugin, then enable it from the Anomify plugin settings page. All plugin integrations are disabled by default.</p>
<p>Metrics generated from plugins are automatically prefixed with “plugin.{plugin_name}.” e.g. “plugin.woocommerce.”.</p>
<p>These integrations are works in progress. If you find them useful, <a href="https://wordpress.org/support/plugin/anomify/" rel="ugc">please let us know</a> as it will help us to prioritise further development.</p>
<h3>WP Statistics</h3>
<p><a href="https://wordpress.org/plugins/wp-statistics/" rel="ugc">Plugin page</a></p>
<p>Metrics that Anomify will collect:</p>
<ul>
<li>visitor.new – number of new visitors today</li>
<li>visitor.returning – number of return visitors today</li>
<li>visitor.country.$country_code – number of visitors from country with ISO code $country_code e.g. “ca”</li>
<li>visitor.agent.$agent – number of visitors using user agent $agent e.g. “chrome”</li>
<li>visitor.device.$device – number of visitors using device type $device e.g. “desktop”</li>
<li>visitor.platform.$platform – number of visitors using platform $platform e.g. “windows”</li>
<li>exclusion.$exclusion_reason – number of requests which are excluded from visit counts due to $exclusion_reason e.g. “robot”</li>
</ul>
<p>Metrics from this plugin are prefixed with “plugin.wp-statistics”, e.g. “plugin.wp-statistics.visitor.new”</p>
<h3>WooCommerce</h3>
<p><a href="https://wordpress.org/plugins/woocommerce/" rel="ugc">Plugin page</a></p>
<p>Metrics that Anomify will collect:</p>
<ul>
<li>cart.added</li>
<li>cart.emptied</li>
<li>cart.updated</li>
<li>customer.created</li>
<li>customer.deleted</li>
<li>customer.password.reset</li>
<li>order.cancelled</li>
<li>order.created</li>
<li>payment.complete</li>
</ul>
<p>Metrics from this plugin are prefixed with “plugin.woocommerce”, e.g. “plugin.woocommerce.payment.complete”</p>
<h3>For plugin developers</h3>
<p>If you want to send metrics from your own plugin, install the Anomify plugin, and use the following syntax in your own code:</p>
<pre><code>do_action('anomify_increment_plugin_metric', 'my.metric.name');
</code></pre>
<p>Or to increment the metric by a value other than 1, e.g. 5, add an optional third parameter:</p>
<pre><code>do_action('anomify_increment_plugin_metric', 'my.metric.name', 5);
</code></pre>
<p>The name of your plugin will be automatically prepended to the metric name so you don’t need to include it in the name that you pass.</p>
<h4>Features</h4>
