OxCal > Analysis
This part of the manual covers the different forms of analysis which can be performed using OxCal. The details of how to enter this information in OxCal is covered in Input of information and the data viewing tools are explained in Viewing output. Throughout this portion of the manual all analysis functions are described in terms of the CQL commands that you need to enter in OxCal to perform the operations. The project manager is designed to help with putting together such code for specific purposes.
Throughout this document there are examples of code to perform certain operations. These are shown in a dialogue box which looks like this:
Assuming the help was opened from the OxCalInput utility, if you click on the button the code will be inserted into the input window and can be run or incorporated into another model. This will enable you to see what the code looks like in the different views and the output can be viewed in the output viewer.
OxCal is designed to be a flexible analysis program for application in a whole range of chronological research. The program is capable of performing simple calculations both on ordinary real numbers and on parameters which have an uncertainty associated with them. In this sense the program can act as an uncertainty calculator for any purpose. There are also specific functions designed for chronological applications, including most obviously the R_Date function for the calibration of radiocarbon radiocarbon dates. Finally there are models which can be applied to the data, such as sequences, deposition models et cetera. The program actually performs these in three stages:
In considering the analysis process it is worth breaking down the operations into several different conceptual stages:
Once you have specified the analysis in this way the analysis is submitted to the OxCal analysis program and the three stage analysis is carried out. This generates output in three different files:
The output utility provided with OxCal allows you to read these three files and to present the data in a number of different ways.
