+<h1>Welcome to the Rnaught web application</h1>
+<p>
+ Rnaught is an R package and web application for estimating the
+ <a href="https://en.wikipedia.org/wiki/Basic_reproduction_number" target="_blank">basic reproduction number</a>
+ of infectious diseases. For information about using this application, view the
+ <span class="fw-bold text-primary">Help <span class="glyphicon glyphicon-question-sign"></span></span> tab.
+ To learn more about the package, visit the online
+ <a href="https://MI2YorkU.github.io/Rnaught" target="_blank">documentation</a> or
+ <a href="https://github.com/MI2YorkU/Rnaught" target="_blank">GitHub</a> repository.
+ Technical details about the estimators featured in this project can be found in the reference
+ <a href="https://doi.org/10.1371/journal.pone.0269306" target="_blank">article</a>.
+</p>
+<h4>What is the basic reproduction number?</h4>
+<p>
+ The basic reproduction number, denoted <em>R</em><sub>0</sub>, is defined as the expected number of infections caused
+ by a single infectious individual when introduced into a totally susceptible population. It assumes that all
+ individuals in a given population are susceptible to the disease, and that no preventive measures (such as lockdowns
+ or vaccinations) have been enforced. It is a useful indicator of the transmissibility of an infectious disease during
+ the early stages of its spread and detection.
+</p>
+<p>
+ If <em>R</em><sub>0</sub> &lt; 1, the disease will eventually die out. On the other hand, if
+ <em>R</em><sub>0</sub> &gt; 1, the disease will spread (the higher the <em>R</em><sub>0</sub>, the faster this will
+ happen). Due to uncertainty of known data about the disease, it is difficult to determine <em>R</em><sub>0</sub>
+ precisely. Therefore, many estimation methods exist, each based on different assumptions and yielding different
+ estimates. It is the responsibility of users to employ the most appropriate estimator (or suite of estimators) given
+ the situation at hand.
+</p>

+The Incidence Decay and Exponential Adjustment (ID) estimator is an alternative formulation of the Incidence Decay (ID) model which includes a decay factor to reflect the often observed outbreak decline.
+This addresses the potential underestimation of the <em>R</em><sub>0</sub> estimate when using the ID method.
+The method of least squares is used to estimate <em>R</em><sub>0</sub>, and similar to the ID model, the serial interval is assumed to be known and this method is developed assuming the SIR model.

+The sequential Bayes (seqB) estimator uses a Bayesian approach to estimate <em>R</em><sub>0</sub> which updates the reproductive number estimate as data accumulates over time.
+This approach is based on the SIR model, and assumes that the mean of the serial distribution (ie. the serial interval (SI)) is known.
+It is assumed that infectious counts are observed at periodic times (ie. daily, weekly).
+This method cannot handle datasets where there are no new infections observed in a time interval, thus, to remedy this,
+some manipulation may be necessary to make the times at which infectious counts are observed sufficiently course (ie. weeks instead of days).
+Further, this method is also inappropriate in situations where long intervals between cases are observed in the initial stages of the epidemic.
+Finally, the <em>R</em><sub>0</sub> approximation behaves similarly to a branching process, which means that throughout, the population size “available” to be infected remains constant.
+We note that this assumption does not hold for the SIR/SEIR/SEAIR compartmental models.
+As such, seqB estimates should only really be considered early on in an epidemic, ie. before the inflection point of an epidemic, if the dataset being used follows these models.

+ The serial interval (SI) is not one of the estimators. It is a parameter required by most of the estimators, and can
+ also be estimated by some of them (if not specified).
+</p>
+<p>
+ The SI is defined as the average time between successive infections in a chain of transmission (i.e., the time between
+ the infection of an infected individual and their subsequent transmissions).
