E-20 Data Input Precautions • S S inputs the same data twice . •Y ou can also input m ultiple entries of the same data us- ing A G . To input the data 110 ten times, f or e xample , press 110 A G 10 S . • The abov e results can be obtained in an y order , and not necessarily that shown abov e .
E-21 •L inear Regression The regression f or mula f or linear regression is: y A B x . • Example: Atmospheric Pressure vs. T emperature Pe rform linear regression to deter- mine the regression f or m ula terms and correlation coefficient for the data nearb y .
E-22 • Example: Pe rfor m quadratic regression to de- ter mine the regression formula terms and correlation coefficient for the data nearby . Next, use the reg ression for- mu la to estimate the values f or ˆ y ( es- timated value of y ) for x i = 16 and ˆ x (estimated value of x ) f or y i = 20.
E-23 Formula Memory (fx- 85W) •F ormula memor y lets y ou input a single for mula in memor y , and then input v alues for the formula's v ar iables to calculate results. •M emory can hold a single f or m ula, up to 79 steps long. This function can be used in the COMP mode only .
E-24 •Y ou can use the follo wing logical operators between values in Base- n calculations: and (logical product), or (logical sum), xor (exclusive logical sum), xnor (e xclu- sive logical sum negation), Not (negation), and Neg (min us). • The following are the allowab le ranges for each of the av ailab le n umber systems.
E-25 Degrees, Min utes, Seconds Calculations •Y ou can perf or m se xagesimal calculations using deg rees (hours), min utes , and seconds, and convert between sexagesimal and decimal values . • Example 1: To con ver t the decimal value 2.258 to a sexagesimal v alue 2.
