topconfidence_band
result = confidence_band(x, y [, confidence=confidence] [, PLOT=PLOT] [, RESIDUAL=RESIDUAL] [, REG_EQ=REG_EQ] [, OPLOT=OPLOT] [, EQUATION=EQUATION] [, CORRELATION=CORRELATION] [, LINESTYLE=LINESTYLE] [, PSYM=PSYM] [, NAN=NAN] [, _EXTRA=_EXTRA])
compute and optionally plot the confidence bands on a regression plot
currently only works for single regression
Return value
structure of points for the confidence bands at the points passed in in x Structure format is: YTOP DOUBLE Array[N_ELEMENTS(x)] YBOT DOUBLE Array[N_ELEMETNS(x)]
Parameters
- x in required
'x' values to regress against
- y in required
'y' values to regress
Keywords
- confidence in optional
set this to specify the conidence band (default 0.95)
- PLOT in optional
set this to plot the data
- RESIDUAL in optional
input the residualts instead of calculation them
- REG_EQ in optional
input a regression equation found externally
- OPLOT in optional
oplot the confidence band on an exsisting plot
- EQUATION in optional
show the equation on the plot
- CORRELATION in optional
returns the correlation coefficient of regression
- LINESTYLE in optional
linestyle of the confidence bands
- PSYM in optional
specifiy the symbol to use when plotting the points
- NAN in optional
pull out any nan data
- _EXTRA in optional
extra keywords to plot
Examples
a=confidence_band(findgen(10)+randomn(seed, 10), findgen(10), /plot)
