Working with ANOVA for data entry in this way is not as straightforward because dimension is required for the analysis on data stored in the list variable. For more casual data entry that command line input is suffice, raw data are usually stored into list variable using c() command. There are also other supported formats including SPSS and Excel. In R, data are usually imported from CSV file using read.csv() command. Using a sample from the classical TI-89 statistics guide book on determining the interaction between two factors using 2-way ANOVA, the same output is obtained from the TI nspire CX. The data can also be named by columns and recalled from the Calculator application. Statistical functions can then be applied. In TI nspire CX, the application Lists & Spreadsheet provided a convenient Excel list interface for data input. Cryptographic roots in Blockchain technology This entry was posted in finance, Statistics, TI Nspire CX CAS, Uncategorized, Visualization and tagged Black-Scholes, TI nspire on Octoby gmgolem. An additional slider control can easily be added on it to adjust an offset variable so as to visualize scenarios under different spot price. This spreadsheet input screen stores the spot prices and the calculated Black Scholes vega values.įinally, with the data plotting screen the graph of Delta hedged gains of volatility sensitivity is completed. The following setup on the Nspire provided the functions to calculate the vega values. Since this strategy involved a single call option, the volatility exposure equals the vega value of the option. The built-in facility like input slider for variable value adjustment allowed dynamic visualization to complex equations, like the volatility sensitivity in delta-hedged gains used financial investment. The TI Nspire calculator is a great platform for visualizing data via interactive graphs.
