Class DataSource

java.lang.Object
  jhpro.stat.DataSource

All Implemented Interfaces:

Serializable, Cloneable

public class DataSource
extends Object
implements Cloneable, Serializable

This class serves as input for the Limit.ComputeLimit method. It takes the signal, background and data histograms to form a channel. More channels can be added using AddChannel(), as well as different systematics sources.

Constructor Detail

DataSource

public DataSource()

Simplest constructor. Use addChannel to add data.

DataSource

public DataSource(H1D s,
                  H1D b,
                  H1D d)

Adds one channel with signal, background and data given as input. Systematic is assumed to be zero for data, signal and background.

Parameters:

s - Signal histogram

b - Background histogram

d - Observed data histogram

DataSource

public DataSource(P1D s,
                  P1D b,
                  P1D d)

Adds one channel with signal, background and data given as input. Systematic is assumed to be zero for data, signal and background.

Parameters:

s - Signal

b - Background

d - Data

DataSource

public DataSource(H1D s,
                  H1D b,
                  H1D d,
                  double es,
                  double eb,
                  double ed,
                  String name)

Another constructor, directly adds one channel with signal, background and data given as input. One can specify systematic uncertainty for signal, background and data. For example, 0.05 value for signal means that signal should be scaled up by 5%. If it is -0.05, signal should be scaled down by 0.05%.

Parameters:

s - Signal histogram

b - Background histogram

d - Data histogram

es - Error on signal

eb - Error on background

ed - Error on data

name - name indicating this systematics

Method Detail

clone

public Object clone()

Allow cloning

Overrides:

clone in class Object

addChannel

public void addChannel(H1D s,
                       H1D b,
                       H1D d)

Adds a channel with signal, background and data given as input. All systematic errors are assumed to be 0.

Parameters:

s - Signal histogram

b - Background histogram

d - Observed data histogram

addChannel

public void addChannel(P1D s,
                       P1D b,
                       P1D d)

Adds a channel with signal, background and data given as input. All systematic errors are set to zero. The name is set to the channel number.

Parameters:

s - Signal

b - Background

d - Data

addChannel

public void addChannel(DataKeeper s,
                       DataKeeper b,
                       DataKeeper d,
                       double es,
                       double eb,
                       double ed,
                       String name)

Adds a channel with signal, background and data given as input. One can specify name for this channel and systematic errors. This is the main constructor.

Parameters:

s - Signal expected

b - Background expected

d - Data observed

es - Systematic error on signal

eb - Systematic error on background

ed - Systematic error on data

                       String name)

Adds a channel with signal, background and data given as input. In addition, systematic error can be set for signal, background, data. For example, systematic error 0.05 on background means scaling background by 1+0.05 factor (i.e. added 5% systematics). If it is -0.05, this will scale background by 1-0.05.

Parameters:

s - Signal histogram

b - Background histogram

d - Data histogram

es - Systematic on signal

eb - Systematic on background

ed - Systematic on data

name - Name for this channel

addChannel

public void addChannel(P1D s,

                       String name)

Adds a channel with signal, background and data given as input. In addition, error sources are defined. TH1 are here used for convenience: each bin has to be seen as an error source (relative). names is an array of strings containing the names of the sources. Sources with the same name are correlated.

Parameters:

s - Expected signal P1D

b - Expected background P1D

d - Measured data P1D

es - systematic on signal

eb - systematic on background

ed - systematic on data

name - name for this channel

swtch -
