Social Science Measurement

I got a solution. There is a error of the commands
options -default_model_dichotomous 1PL

It should be written istead of above command

set_default_model_dichtomous 1PL

(Here, delete "o" between dich and tomous)

And this command should appear before command allocate_items_dist

Therefore the example is

#
# mondaty.tcl
#
# Estimate item parameters for Form Y items
# using data for examinees who took Form Y.
# Example data from Chapters 4 and 6 Kolen and
# Brennan (1995)

# Write output to log file mondaty.out
output -log_file mondaty.log

# Get 1 PL item value instead of default 3 PL value
set_default_model_dichtomous 1PL


# 36 items to be modeled
allocate_items_dist 36

# Read examinee item responses from file mondaty.dat.
# Each record contains the responses to
# 36 items for an examinee in columns 1-36.
read_examinees mondaty.dat 36i1

# Compute starting values for item parameter estimates
starting_values_dichotomous

# Perform EM iterations for computing item parameter estimates.
# Maximum of 50 EM iterations.
EM_steps -max_iter 50

# Print item parameter estimates and discrete latent
# variable distribution.
print -item_param -latent_dist

# end of run
