Description
Simulate fluorescence trace based on simple AR(1) generative model
Usage
1
simulateAR1(n, gam, poisMean, sd, seed)
Arguments
n
number of timesteps
gam
AR(1) decay rate
poisMean
mean for Poisson distributed spikes
sd
standard deviation
seed
random seed
Details
Simulate fluorescence trace based on simple AR(1) generative model
y_t = c_t + eps, eps ~ N(0, sd)
c_t = gam * c_t-1 + s_t
s_t ~ Pois(poisMean)
Value
spikes, fluorescence, and calcium concentration
See Also
Estimate spikes:
estimateSpikes,
print.estimatedSpikes,
plot.estimatedSpikes.
Cross validation:
cv.estimateSpikes,
print.cvSpike,
plot.cvSpike.
Simulation:
simulateAR1,
plot.simdata.
Examples

2
sim <- simulateAR1(n = 500, gam = 0.998, poisMean = 0.009, sd = 0.05, seed = 1)
plot(sim)
